EX60
Car

EX60

The EX60 is a fully electric Volvo car, meaning it runs on a battery instead of gasoline. The podcast context suggests it’s being promoted as a car you can test or experience at a Volvo dealer. Because it’s electric, charging is a key part of owning it.

Term

cigarette lighter

That “cigarette lighter” socket is usually a 12-volt power plug in the car. You can plug camping accessories into it instead of doing any wiring.

Term

hook it straight up to your battery

This means connecting the accessory directly to the car’s battery. It can work better than a plug-in socket, but you need to wire it safely (often with a fuse).

Term

bonnet

A “bonnet” is the car’s front hood. They’re just saying to close it so nothing gets in the way while you set up the accessory.

Term

awning

An awning is the fabric shade cover you put out when camping. They’re attaching the light along that cover.

Term

velcro straps

Velcro straps are the hook-and-loop ties that stick together. They’re using them to fasten the light without tools or permanent brackets.

Term

dim it

“Dim it” means you can lower how bright the light is. That’s useful for comfort and saving power while camping.

Term

seek socket it

This line is a bit unclear in the transcript, but it sounds like they’re talking about a simple plug-in way to connect the light. The main point is making it easy to set up without complex mounting.

Car

Holden 2012 RG Space Cab Colorado

This is a Holden Colorado ute (a 4WD work vehicle). “RG” is the model generation, and “Space Cab” describes the cab layout—basically how many doors and how much room you get in the back.

Term

low range

Low range is a special low gear mode in 4WD trucks. It makes the vehicle move slower but with more “grunt,” which helps when you’re driving off-road or going up difficult terrain.

Term

144 litre tank

A “144 litre tank” refers to a large fuel tank capacity, which increases driving range between refueling stops. For off-road touring, bigger tanks are often paired with long-distance routes where fuel stations are scarce.

Term

high range four wheel drive

High range 4WD is the regular 4WD mode you use for normal driving and easier dirt roads. It doesn’t give as much low-speed pulling power as low range, so it can feel a bit “too tall” when you need to crawl.

Part

bullbar

A bullbar is a strong metal bar on the front of a 4WD. It helps protect the front of the vehicle if you hit something like an animal or debris on rough roads.

Part

side rails

Side rails are protective bars mounted along the sides of a 4WD, typically near the rocker panels. They help guard against damage from brush, rocks, and minor impacts when driving off-road or when squeezing through tight terrain.

Part

king's dominator winch

A winch is basically a powered rope/cable that can pull a vehicle out when it gets stuck. “King’s Dominator” is the name of that winch setup.

Part

144 liter long range tank

A long-range tank is extra fuel capacity so you can drive farther before refueling. “144 liters” means it holds a lot of extra fuel for remote trips.

Term

lithium batteries

Lithium batteries are rechargeable battery packs that store electricity. They’re commonly used in car builds because they can hold a lot of energy in a smaller, lighter package than older battery types.

Term

amp hour

Amp-hour (Ah) tells you how much energy a battery can store. More Ah usually means you can run things for longer before the battery needs to be recharged.

Term

2000 watt

Watts measure how much power something can produce. Here, “2000 watt” is the inverter’s maximum power, which helps you know what appliances you can run from the battery.

Term

pure sine wave inverter

An inverter turns battery power into the kind of electricity your household devices use. A “pure sine wave” inverter produces cleaner power, which helps electronics work properly.

Term

DC DC charger

A DC-DC charger is a device that helps charge one battery from another using DC power. It’s used so the auxiliary battery gets charged safely and effectively while you’re driving.

Term

canyon hard shell

That phrase refers to a rooftop tent with a solid, hard outer shell. It helps keep you drier and more protected from wind and weather while you sleep in the vehicle.

Term

shower tent

A shower tent is a small privacy enclosure you set up at camp. It lets you shower without needing a bathroom or someone else’s facilities.

Term

companion lithium

This sounds like a lithium battery that powers camping gear. It’s used so you can run things like lights or a hot-water system while you’re off-grid.

Term

hot water system

A hot water system is what heats the water and lets you shower while camping. It’s meant for off-grid use, not just at home with a water heater.

Term

no tune or mods

A “tune” means changing the car’s computer settings for how it runs. If they say “no tune or mods,” they mean the engine was left mostly stock and only basic parts were changed.

Term

air box

The air box is the intake housing that helps manage the air going into the engine. Changing it can affect how the engine gets air and can be part of a performance or reliability setup.

Term

unifilter pod filters

Pod filters are aftermarket air filters shaped like small cones. They’re meant to improve or change airflow into the engine, but in dusty off-road conditions they need to be installed and maintained properly.

Brand

Cumforza CF

Cumforza CF appears to be a specific tire model/line used in the build. The “CF” designation helps identify the exact tire construction and tread pattern, which matters because different tire models behave differently in mud, sand, and on-road braking.

Term

mud terrain tires

Mud terrain tires are made for off-road driving. The tread is designed to grip in mud and dirt, though they can be noisier and wear quicker if you mostly drive on pavement.

Term

EFS heavy duty suspension

EFS heavy duty suspension is an upgraded suspension meant for tougher off-road driving. The “40 millimeter” lift means the truck sits higher for more clearance, but it can also change how it drives compared to stock.

Term

40 millimeter

The “40 millimeter” is the amount the suspension lifts the truck. More lift can help the tires clear obstacles, but it can also change how the truck sits and handles.

Brand

outback armor suspension

Outback Armor suspension is a brand of suspension parts. They’re considering it as a replacement option for their current suspension to see how it rides off-road.

Ford Ranger
Car

Ford Ranger

They’re saying they previously used the same suspension setup on a Ford Ranger. Different trucks can react differently to the same suspension parts.

Term

Uniden Pro 80

Uniden Pro 80 is a specific type of radio (a UHF CB) used to talk to other drivers during trips. Putting it on the roof with an antenna helps it reach farther and work better.

Term

UHF

UHF is the radio frequency band used by off-road radios. It’s useful for talking to other cars on trips when phone reception isn’t great.

Term

selfie 5G booster

A 5G booster is a gadget meant to make mobile data work better in areas with weak signal. Here, the host says this particular booster wasn’t worth the money for their use.

Term

RFI 5G antenna

This is an external antenna meant to help a 5G booster receive a stronger signal. Bigger/external antennas can pick up mobile data better than the built-in ones.

Brand

Starlink mini

Starlink mini is satellite internet for when you’re far from mobile towers. The host is using it to stay connected on trips where normal 4G/5G can be unreliable.

Concept

TLC

“TLC” just means taking good care of the vehicle—regular upkeep and servicing. The host is saying their Colorado has been looked after rather than neglected.

Term

pop-up

Here, “pop-up” means the tent opens quickly when you park. Instead of building it from scratch, it unfolds with hinges so you can get set up faster.

Term

hard shell rooftop tents

A hard shell rooftop tent is a tent that sits on top of your vehicle and has a rigid cover that flips open. It usually goes up faster and keeps you drier in bad weather than soft tents.

Term

clam shell

A “clam shell” rooftop tent is a design where the tent opens like a hinged shell—similar to how a clam opens—so the sleeping area unfolds from the roof-mounted base. The shape can help with quick setup and keeping the tent more protected when closed.

Concept

bush rig

A “bush rig” is a vehicle prepared for remote, rugged outback-style trips. It usually means it’s set up with the kind of gear and protection you’d want for dirt roads and camping.

Term

swing out

A “swing out” is a hinged rear attachment that opens outward like a door. It helps you reach things at the back—like a spare tire—without having to unload everything.

Toyota Land Cruiser
Car

Toyota Land Cruiser

“Land Cruisers” are Toyota 4WDs that many people use for serious off-road and long-distance trips. They’re being used here as the traditional alternative to the Colorado.

Term

push rig

A “push rig” is a 4WD that’s set up to handle harder trips and rough conditions. It’s the kind of build meant for getting out into remote areas with the gear you need.

Concept

long range of fuel tank

“Long range” just means the vehicle can go farther before needing fuel. For outback trips, that’s important because fuel stations can be far apart.

Term

GVM

GVM means the maximum total weight your vehicle is allowed to be when it’s loaded. If it’s “over GVM,” that means the car may be too heavy for what it’s rated for, which can be unsafe and can also cause legal issues.

Term

economy

Here, “economy” means fuel economy—how many kilometers you get per tank. If you add heavy gear and accessories, the 4WD often has to work harder, so it can use more fuel.

Term

stress

Here “stress” means extra strain on the car from added weight or loads. The idea is to avoid bolting on stuff that makes the front end work harder than it needs to.

Term

weight on the roof

When you put heavy stuff on the roof, it sits higher up on the car. That can make the vehicle feel less stable—especially on rough roads—because the car’s balance point changes.

Prado / Meru
Car

Prado / Meru

Prado and Meru are SUV names used for Toyota vehicles. They’re typically the kind of cars people choose when they want more capability for rough roads or off-road driving. In the podcast, they’re likely just being referenced as examples of 4WD-capable vehicles.

Place

Perth

Perth is a city in Western Australia. They’re talking about where you can rent a 4WD and where you might be able to drop it off for a camping trip.

Toyota Corolla
Car

Toyota Corolla

A Corolla is a regular car, not a serious off-road 4x4. The idea here is that you can’t really use it like a proper camping 4WD vehicle.

Company

Adventure West 4x4 Rentals

Adventure West 4x4 Rentals is a company that rents out 4-wheel-drive vehicles. They’re being used as an example of where you might book a 4WD for a camping trip.

Company

4 Exploring Rentals

4 Exploring Rentals is another company that rents out 4-wheel-drive vehicles. They’re mentioned as an option for booking a 4WD from the Perth area.

Place

Esperance

Esperance is a town in Western Australia. They’re wondering whether 4WD rental companies can provide vehicles to that area or handle drop-offs there.

Term

loud V8

A V8 is an engine with eight cylinders. People who want a “loud V8” usually mean they want the car to sound more aggressive, often by changing the exhaust.

Term

track correction

Track correction is about making sure the wheels are set up correctly. If you change rims or wheel offset, you may need track correction so the car drives straight and the tires wear evenly.

Term

offset rim

An offset rim means the wheel sits more in or more out compared to stock. That can change how the tires fit under the car and how the vehicle handles, so it sometimes requires follow-up adjustments.

Term

canopy

A canopy is a box-like cover on the back of a ute. It gives you enclosed storage and can be set up for camping gear and power.

Term

long range fuel tank

A long range fuel tank is extra fuel capacity for your 4WD. It helps you go farther in remote areas without needing to find fuel quickly.

Concept

mods that you and I have done to our cars

They’re basically saying mods are only worth it if you’re using them for a reason. If you’re not doing the kind of trips that need the gear, it’s probably not a good idea to spend the money.

Concept

for a reason

They’re saying you shouldn’t modify your 4WD just because it looks cool. Each change should help you do the kind of driving you actually plan to do.

Term

battery set up

A “battery set up” is how you power extra stuff in your 4WD. People often add a second battery so they can run things like a fridge or lights without draining the main starting battery.

Term

bigger tyres

“Bigger tyres” means larger tires than the factory ones. They can help your 4WD clear obstacles and grip better off-road, but they can also affect how the car’s speed and gearing feel.

Term

all terrains

“All terrains” are tires made for mixed driving. They’re meant to be decent on the road but still handle dirt and gravel better than normal street tires.

Term

lift

A “lift” means raising your 4WD so it sits higher. That can help it clear rocks and ruts, and it usually goes along with other changes like tire size and suspension setup.
