Suzuki Vitara
Car

Suzuki Vitara

The Suzuki Vitara is a small SUV that can handle more than just smooth roads. The podcast mentions an older two-door soft-top version that the speaker used for rough driving. That’s why it’s brought up—because it was used for off-road-style fun.

Concept

lemon

A “lemon” is a car that turns out to be a bad one—usually because it keeps having problems. The host is saying his Prado was like that.

Term

rust and black paint over the rust

If someone paints over rust, it can be a sign they’re trying to cover up damage instead of fixing it. Rust can keep spreading underneath the paint.

Topic

surfing

They mention going surfing to explain the trip they took and what went wrong with the car. It’s just the story context for the vehicle damage.

Toyota Prado
Car

Toyota Prado

The Toyota Prado is a 4WD SUV built for driving off-road. In this segment, it sounds like the car was used for a trip where it shouldn’t have been pushed, and something important broke.

Term

four wheel drive constant

“Constant four-wheel drive” means the car is sending power to all four wheels all the time. It helps with traction, but if parts are damaged or the route is too rough, things can still break.

Part

shock absorber

A shock absorber is the part that helps your suspension stay controlled over bumps. If it breaks, the car can bounce or feel unstable, and it can make driving much less safe.

Term

oil leak

An oil leak means engine oil is escaping from seals, gaskets, or other components. Depending on where it’s coming from, it can range from a relatively straightforward fix to a serious issue that risks low oil pressure and engine damage.

Term

engine out

“Engine out” means the mechanic has to take the engine out of the car to fix something. It usually means the repair is bigger and more expensive than a simple fix.

Part

engine mounts

Engine mounts hold the engine in place and help reduce vibration. If they break, the engine can move around more than it should, which can lead to bigger problems.

Car

BT-50 Bt50

The Mazda BT-50 is a pickup truck that’s meant for work and rougher driving. In this segment, it’s the truck the host was trying to get next.

120 series Prado
Car

120 series Prado

A “120 series Prado” is a Toyota off-road SUV generation that a lot of people use for road trips and rougher driving. The speaker liked how it drove, but they’re saying their own particular one had problems.

Term

locker

A locker is a device that helps both wheels on an axle turn together. If one wheel starts spinning in mud or rocks, the locker helps the other wheel keep moving. They’re saying you only need it for certain tricky parts of the trail.

Term

scraped my chassis

Scraping the chassis means the bottom of the car hit the ground. That can happen when the trail has steep dips or bumps. It can damage the underside, so it’s a sign the obstacle was really tough.

Term

rock stacking

Rock stacking means putting rocks under the tires to help the car get grip and move. It can give the wheels something firmer to roll over. They tried it as one of the ways to get unstuck.

Term

traction

Traction is how well the tires grip the ground. If you don’t have traction, the wheels spin and the car won’t move. They’re talking about trying to get the back tires to grip so they can get unstuck.

Term

winch

A winch is a motor that pulls a heavy cable. Off-road, people use it to pull their car out when it’s stuck in mud or sand.

Term

tree protector

A tree protector is something you put around a tree so the winch cable doesn’t damage it. It also helps keep the recovery setup safer and cleaner.

Term

bull bar

A bull bar is a heavy-duty front guard on a 4x4. It helps protect the front of the vehicle, but it can get in the way when you’re setting up recovery gear.

Term

warning light

Warning lights are dashboard indicators that alert the driver to faults or system problems. When a vehicle is flooded or electrical components get wet, multiple warning lights can illuminate at once because sensors and control modules detect abnormal conditions.

Term

snatch straps

Snatch straps are stretchy straps used to tow or pull a stuck car. Another vehicle pulls them, and the stretch helps yank the stuck vehicle free—done carefully and safely.

Term

positive terminal

A battery has two main connection points: positive (+) and negative (-). The positive terminal is the one that feeds power to the car’s electrical system, so problems there can affect lots of things at once.

Term

fuse box

A fuse box is where the car keeps safety devices for the wiring. Each fuse protects a different electrical system, so if one fuse is bad, that part of the car won’t work.

Term

diesel

Diesel engines don’t use spark plugs to ignite fuel, but they still usually need the battery to start and run the electronics. So the idea that a diesel can run without a battery is only true in limited, older situations.

Term

snorkel

A snorkel is a raised air intake for off-roading. It lets the engine pull air from higher up, so you can drive through deeper water without water getting into the intake.

Term

blade fuse

A blade fuse is a typical car fuse you can pull out and replace. In this case, the fuse is built into the battery terminal, so you can’t just replace the fuse element—you have to fix/replace the whole part.

Term

fuel filter

A fuel filter is like a strainer for your fuel. It helps stop dirt and other junk from getting to the engine. Here, they’re saying water was getting into that filter area, so they had to remove it repeatedly.

Term

water separator

A water separator is a part in the fuel system that catches water before it gets to the engine. Water in fuel can cause the engine to run badly or not start. It usually lets you drain out the collected water.

Term

hydro lock

Hydro lock means water got into the engine where it normally only has air and fuel. Because water doesn’t compress like air, the engine can’t move the pistons properly and can cause serious damage. It’s one of the big fears after driving through water.

Term

wet vac

A wet vac is a vacuum that can suck up water, not just dust. After the car got flooded, they used it to remove water from the carpet so it could dry out and not smell or grow mold.

Term

carpet

Carpet can soak up water and hold onto it for a long time. Even if it looks dry, the padding underneath can still be wet. That can lead to bad smells or mold if you don’t dry it out properly.

Term

insulation

The insulation under the carpet can act like a sponge and keep water inside. So even after you think it’s dried, it may still be wet underneath. That’s why they kept pulling water out and letting it dry again.

Term

canvas canopy

A canvas canopy is a fabric cover you put over the back of a vehicle to help keep gear protected from weather. It’s common on camping setups because it’s practical and can be customized.

Term

WAU1

“WAU1” here is probably a label or model code for the exact canopy setup being discussed. It’s not a general car term—more like a product/config name.

Term

manuals online

Factory service manuals (often found online) are detailed documents that show wiring diagrams, component locations, and step-by-step repair procedures. Corey mentions using them as a learning tool for his 60 Series because he doesn’t know much yet.

Term

canopy camper

A canopy camper is a camping add-on that sits on top of a ute. It turns the truck into a place to sleep and store gear without needing a full vehicle conversion.

Term

rooftop tent

A rooftop tent is a tent that sits on the roof of the vehicle. When you park, you open it up to sleep inside.

Concept

poor man's troopy

“Poor man’s troopy” is a joking way to say “this setup gives you the same camping vibe as a Troopy,” but cheaper. They’re comparing their ute camper to a well-known Toyota camping rig.

Term

Alibaba

Alibaba is a website where you can buy products from suppliers, including overseas. They’re using it to order the camper setup and have it shipped to them.

Term

induction cooktop

An induction cooktop cooks by using magnet heat in the pan, not a flame. It’s efficient and heats up fast, which can be handy when you’re cooking in a camper setup.

Term

mesh

Here “mesh” means a screen/vent opening. It lets air move out so cooking smells and grease can vent while still blocking bugs.

Concept

lap of Australia

“Lap of Australia” means a big, long road trip around Australia. They’re saying this setup is meant for that kind of extended travel, not just short weekends.

Term

rivnuts

Rivnuts are a type of fastener that gives you a threaded hole in sheet metal. They’re useful for camper builds because you can bolt things together tightly.

Term

reinforced frame

A reinforced frame is extra strengthening built into the structure. The host is saying the canopy alone isn’t stiff enough, so they add support so the tent mount is solid.

Brand

Porsche

Porsche is being used as a reference point for design—specifically how the brand’s styling can be visually compelling even to someone who doesn’t usually like supercars. In this segment, it’s part of the argument that the Toyota Land Cruiser 60/80 series have standout looks.

Term

three day printing

They mean 3D printing parts that take about three days to finish. It’s how you can make custom interior pieces that match your exact design and fit.

Term

center console

The center console is the panel between the front seats. It often includes the shifter and storage, and in this case they’re modifying it because it doesn’t let you comfortably rest your arm.

Term

gear shifter

The gear shifter is the lever you move to choose gears. They’re talking about where it sits so their custom console and armrest can line up with it.

Term

3D modeling

3D modeling means making a digital 3D version of a part on a computer. Builders use it to design custom pieces that will fit correctly before they print or build them.

Tesla 3D Model
Part

swivel hubs

Swivel hubs are parts in the front axle that let the wheels turn. If they’re worn, the steering can feel loose or noisy, so builders often replace or rebuild them.

Part

wheel bearing

Wheel bearings are small parts that help your wheels rotate smoothly. If they wear out, you can get noise or rough steering, so people replace them during a build.

Part

new lift

A lift means raising the truck higher off the ground. People do it so they can clear obstacles better and often fit bigger tires.

Brand

ARB compressor

ARB makes off-road gear, including air compressors. Here, the compressor provides air pressure to operate the lockers.

Term

dual battery system

A dual battery system means you have two batteries—one for starting and one for accessories. It helps you run camping gear without risking the car won’t start.

Term

lithium

Lithium batteries are a type of car battery that can be lighter and let you use more of the battery before it’s “empty.” People like them for camping power setups.

Term

bed in the back

They’re planning to turn the back of the vehicle into a place to sleep or relax. The idea is a fold-out setup so it’s comfortable when parked.

Term

concertina's up

They’re describing an accordion-style folding motion. The goal is to make the bed fold up compactly and then open out when you’re parked.

Term

patina

“Patina” means the worn-in, aged look a vehicle gets over time. Here, they’re saying the paint wear might be considered “patina,” but the host also suggests it’s actually getting worse rather than being a planned style.

Part

farm bar

A “farm bar” is a protective bar on the front of a 4WD. It’s there to help protect the vehicle if you hit something on the road, like an animal, and the host says theirs is temporary while they’re planning the next steps.

Term

panel work

Panel work is the metal-and-body repair on a car—fixing dents, replacing sections, and getting the surface ready for paint. Good panel work also helps prevent rust from coming back.

Term

blind spot

A blind spot is a part of the road around your car that you can’t see from the driver’s seat. Better window design can reduce blind spots and make driving feel safer and easier.

Term

auto

“Auto” means the car shifts gears by itself. A manual requires you to change gears, so the driving experience is different.

Term

turbo

A “turbo” is a device that helps the engine make more power. It uses the car’s exhaust to spin a fan that pushes extra air into the engine so it can burn more fuel.

Term

12 HT

“12 HT” is an engine code/name. Here it’s being used to talk about a turbo engine and how it feels with different transmission types.

Concept

white labelled

“White labelled” means selling a product made by another company under your own brand name with minimal changes. In automotive accessory terms, it’s common for brands to rebrand existing designs rather than engineer and manufacture their own.

Brand

packed

“Packed” is the name of the brand for the bags being discussed. The host says they started it so they could control the product and build an audience around it.

Term

Cape York

Cape York is a remote part of Australia where people go on big 4WD road trips. It’s known for rough tracks and river crossings, so your vehicle needs to handle water and uneven ground.

Term

river crossing

A river crossing in 4WD travel is when you drive through water that can be deep enough to reach the front of the vehicle. It’s a key risk point because water can affect traction, enter components, and cause the vehicle to stall or get damaged if you misjudge depth and flow.

Term

two inch lift

A “two inch lift” means the suspension is raised so the car sits higher. That extra height helps the vehicle clear rocks and helps with deeper water crossings.

Term

grill

The grill is the front part with openings where air goes through. If water reaches that area, it usually means the crossing is deep enough to start causing problems.

Term

bonnet

The bonnet is the front hood of the car. When people say water is “going over the bonnet,” they mean it’s getting deep enough to reach very high on the vehicle, which can be dangerous.

Term

76 or a 79

“76 or 79” refers to two versions of the Toyota Land Cruiser that are common for outback trips. They’re being used here to say those models handle water crossings better than the earlier setup.

Place

Alice South

Alice South is the area/route south of Alice Springs in Australia. It’s a remote drive where the scenery can be amazing, but the road can still be a bit sketchy.

Place

Fink

“Fink” is shorthand for the Finke Desert Race area/event in Australia, which is known for off-road desert racing and filming lots of action. The mention suggests the creators they follow are often at that kind of desert motorsport scene.

Term

slid[e] out fridge slide

A fridge slide is a tray or platform that lets your fridge slide out so you can reach it easily. It’s designed to be secure while driving, but still convenient when you stop.

Term

inverter

An inverter is a device that changes power from your battery so you can use electronics that normally plug into the wall. It’s a key part of making a camping power system more flexible.

Term

tread

Tread is the pattern on the tire that touches the ground. A tire’s tread design changes grip and can also affect how noisy or bumpy it feels, especially at higher speeds.

Term

muddies

“Muddies” usually means mud-terrain tires. They’re made to bite into soft ground like mud or clay and to clear mud out of the tread so you don’t lose traction.

Term

all terrains

All-terrain tires are a tire type made to handle both normal roads and dirt/sand. They have tread that grips better off-road, but they can be louder or feel a bit different on the highway.

Ford Ranger
Car

Ford Ranger

The Ford Ranger is a pickup truck that can be used for normal driving and also for rougher roads. People talk about it because it’s comfortable to drive, but it can still handle off-road situations. That mix is usually what makes it a common choice for 4WD fans.

Term

transmission tunnel

The transmission tunnel is the raised section in the floor where the drivetrain components sit. People add accessories there because it’s a natural space for extra storage.

Toyota Land Cruiser
Car

Toyota Land Cruiser

The Toyota Land Cruiser is a tough 4x4 that people often modify for off-road trips. Here, it’s mentioned as the type of vehicle the speaker is designing something for.

Place

Shark Bay

Shark Bay is a place in Western Australia with beaches and great fishing. The host talks about it as a fun spot because the sand is soft and the fishing can be really good.

Place

Dirk Hartle

Dirk Hartog is a remote island off Western Australia. The speaker describes going there for fishing and camping, including a solo trip.

Jeep Wrangler
Car

Jeep Wrangler

The Jeep Wrangler is a 4-wheel-drive vehicle made for off-road driving. It’s built to handle rough trails and is often chosen by people who want a vehicle that can go off the beaten path. In the conversation, it’s mentioned as a particular Wrangler that was sent for review or discussion.

Term

drifts

“Drifts” means the driver makes the car slide sideways on purpose. The goal is to keep control while the rear wheels lose grip.

Term

slicks

“Slicks” are special race tires with little to no tread. They grip really well on dry track surfaces, but they’re not great for wet roads.

Term

green smoke

“Green smoke” typically points to exhaust smoke from combustion issues or additives, often seen when a car is being pushed hard (like during drifting) or when there’s an intentional/observed smoke effect. The color can be a clue to what’s burning or being introduced.

Person

Sean Scott

Sean Scott is a person the host says they used to follow online. He’s described as someone who makes a lot of vehicle-related videos.

Brand

Loader

“Loader” is mentioned like a sponsor. That usually means a company is helping support the creator or the vehicle content.
