A skid steer is a compact construction machine that turns by skidding its wheels (or tracks) rather than using a steering wheel like a car. It’s designed to be maneuverable in tight spaces and is commonly used with interchangeable attachments for tasks like digging, lifting, and grading.

An excavator is a heavy construction machine built around a boom and arm with a bucket for digging and moving material. Compared with a skid steer, excavators are typically better suited for longer-reach digging and heavier earthmoving work.

Attachments are interchangeable tools mounted to a machine (like a skid steer/excavator) to change what it can do. Examples mentioned here include tools for logging, building, and road building, which let the same base machine handle many different jobs.

Marketplace refers to an online listing platform where used equipment can be bought and sold. Here it’s used as evidence that the dealer has listings, which influences the host’s idea of negotiating for a used machine.

Mechalac is a brand/model family of compact construction machines known for a distinctive articulated arm and wheel/track setup. In this segment, they describe it as a “crazy arm with these wheels,” and it’s positioned as a hybrid between a skid steer and an excavator.

The hosts describe a trip to Moab and Arches, including off-road driving in a 4x4 van. This functions as a travel story that explains why they became interested in four-wheel-drive camper vans.

Four-wheel-drive camper vans are vans built for both living in (camping) and off-road traction. The key idea is that the drivetrain can send power to all four wheels, helping the van move over loose dirt, sand, or uneven terrain.

An eFoil is an electric hydrofoil board that uses a motor to lift the rider above the water on wing-like “foils.” Because it’s electric, it’s typically quieter than gas-powered watercraft and can be used in places where noise is a concern.

“Flow rate” is how much fluid (usually hydraulic fluid in an excavator) moves through a system per unit time. When people try to increase flow rate, they’re typically trying to make hydraulic attachments move faster or work more aggressively.

“Logging protection” here refers to protective hardware used to shield glass or other exposed parts during logging-related work. The hosts connect it to a “cage” product that goes over glass to prevent damage from debris or impacts.

Duramax is GM’s turbo-diesel engine line used in many heavy-duty trucks. It’s especially valued for torque (the twisting force that helps with towing and moving heavy loads) and for feeling smooth under steady driving.

“6.6” refers to engine displacement in liters for the Duramax (a 6.6-liter diesel). Larger displacement often helps produce strong torque, which is why big diesel engines are common in heavy-duty trucks.

Two turbos means the engine uses twin turbochargers to force more air into the cylinders. This can improve power and torque across a wider range of engine speeds compared with a single turbo setup.

Air ride suspension uses compressed air instead of traditional steel springs to support the vehicle. It can smooth out bumps and help maintain ride height, which is especially helpful for heavy vehicles like ambulances that need consistent comfort and control.

An external air compressor is the pump that pressurizes the air system used by air ride suspension. If it fails—or if there are air leaks—pressure can’t be maintained, and the suspension can lose its intended ride height and smoothness.

An onboard air compressor is a small pump mounted in the vehicle that pressurizes air for pneumatic systems. In this case, it supplies air to the rear air suspension/airbags and the air for the seats, so it directly affects ride height and comfort functions.

“Rear airbags” here refers to air springs at the back of the vehicle, not just crash airbags. Air springs use pressurized air to support the vehicle’s weight and help smooth out bumps, and they’re commonly paired with an onboard compressor and valves.

A low coolant light is a dashboard warning indicating the engine’s cooling system has insufficient coolant. Coolant is what carries heat away from the engine, so low levels can risk overheating.

“Low coolant” means the engine cooling system doesn’t have enough liquid to carry heat away. When coolant level drops, the system can’t maintain proper temperature control, which can trigger overheating warnings even if the engine isn’t fully boiling yet.

A “pressurized cap” on the radiator maintains system pressure. Higher pressure raises the coolant’s boiling point, so the engine can run hotter without the coolant turning into steam.

An “expansion tank” is a reservoir connected to the cooling system that receives coolant/pressure when the engine heats up. As temperatures drop, it draws coolant back in to keep the system filled and stable.

“Chevy” refers to Chevrolet, which the host says uses a cooling-system design with a pressurized expansion tank rather than the more traditional radiator cap approach. This matters because the pressure-management strategy affects how the system behaves when coolant level or pressure is off.

Volkswagen is mentioned as using a cooling-system layout the host describes as having a pressurized expansion tank. The point is that different manufacturers manage cooling-system pressure differently, which can change how alarms and coolant loss present.

An “air leak” in a pressurized cooling system can prevent the system from building and maintaining pressure. Without proper pressure, coolant can boil at a lower temperature and turn into steam, which looks like coolant disappearing.

“Coolant lines” are the hoses and tubing that route coolant through the engine and heat-management components. If air leaks or pressure loss occurs in these lines, the system may not build pressure and can boil or trigger alarms.

“Heater hoses” carry hot coolant to the cabin heater core. Because they’re part of the same cooling circuit, leaks or air pockets in heater hoses can contribute to low-pressure operation and coolant loss.

Coolant “boils at a significantly lower pressure” when the cooling system can’t maintain pressure. Lower pressure reduces the boiling point, so the coolant can transition to steam more easily, leading to coolant loss.

“Steam and boil off” describes coolant turning into vapor and escaping into the atmosphere. In a failing cooling system, this can happen gradually, making it look like the car is “using coolant” without obvious puddles.

The hosts describe using an ambulance for a real-world errand/appointment drop-off. This sets up the context for why they were monitoring the vehicle’s condition and why the situation became urgent.

Head gaskets are the sealing layer between an engine’s cylinder head and the engine block. If they fail, coolant can leak into the combustion chambers or out externally, and the engine may overheat or lose coolant. The hosts are discussing whether the symptoms they’re seeing could be consistent with a head gasket failure.

A pressurized cooling system means the engine’s coolant is held under pressure, which raises the boiling point and helps prevent overheating. When a head gasket fails, pressure can build in the wrong places (like combustion gases entering the cooling system), changing how the system behaves. The hosts use this idea to reason about whether the symptoms match a head gasket issue.

A “hundred mile challenge” is a self-imposed endurance test where the goal is to cover about 100 miles as a way to prove how capable the vehicle is. In this episode, they’re applying that idea to Power Wheels Lamborghini toys to see if they can handle sustained driving.

“Range” is how far the vehicle can travel on a charge. They discuss both the stock battery’s limited distance and the need for batteries that can recharge quickly for repeated runs.

A “40 volt battery” refers to the battery pack’s nominal voltage. In EVs, higher system voltage can change how power is delivered, which can affect acceleration and also how hard the rest of the electronics are working.

A “24 volt system” is the electrical design target the vehicle’s controllers and related electronics were built around. If you run a much higher-voltage battery without retuning, you can get performance changes but potentially create long-term stress or reliability risk.

In an EV conversion or battery swap context, “controllers” are the electronics that manage power delivery from the battery to the motor(s). If you don’t retune them for the new voltage, the car may still run but the behavior and stress levels can change.

“Charge quickly” refers to the battery’s ability to accept power at a high rate, reducing downtime between runs. For event logistics, fast charging can matter as much as peak range.

“Three miles” is the stated usable distance from the stock batteries. It’s a key data point because they later compare it to the total distance context of their event.

“Six hours” is the stated charging time for the stock batteries. Charging time directly impacts how practical the vehicle is for repeated use during a multi-stage event.

“Coolant” is the liquid that carries heat away from the engine to the radiator. A “coolant issue” usually means a leak, overheating risk, or a cooling-system malfunction that can quickly become a reliability problem on a long drive.

Harbor Freight is a retail brand known for selling tools and equipment, including cordless battery platforms. Here it’s mentioned because they bought batteries and used them to power their setup.

Atlas is Harbor Freight’s cordless tool battery line. The segment explains they used Atlas batteries (40V/80V) to run their equipment, which is relevant to how the system is powered and for estimating runtime.

Battery voltage (like “40 volt”) affects how much electrical power can be delivered to tools and how they’re wired. Higher-voltage battery systems can be more efficient for certain high-draw equipment, depending on the tool design.

“Amp hours” (Ah) is a battery capacity rating—how much charge the battery can store. More amp hours generally means the battery can run equipment for longer at a given power draw.

“Miles to the gallon” (MPG) is a fuel-economy measure showing how many miles you can drive per gallon of fuel. It’s especially useful when comparing how different vehicles handle heavy loads like towing or large cargo boxes.

This refers to the vehicle’s gross weight class—an ambulance built to carry heavy equipment and personnel. Weight has a major impact on fuel economy, braking demands, and how hard the engine and transmission have to work.

The Toyota Tundra is a full-size pickup known for towing capability and V6/V8 engine options depending on model year. In this segment, it’s used as a real-world comparison for fuel economy while towing a trailer.

A trailer is an unpowered load-carrying unit towed behind a vehicle. Towing a trailer adds aerodynamic drag and rolling resistance, which typically reduces fuel economy and increases drivetrain load.

The “Gambler 500” is a well-known grassroots rally where participants buy a cheap car and then drive it to a destination, often with a strict budget. It’s become a cult event in the car community because it rewards creativity and risk-taking rather than expensive prep.

A sidecar is an attached passenger compartment mounted to a motorcycle, creating a three-wheeled vehicle. It affects cornering and braking balance, and it’s often used for touring or carrying an additional rider.

“Dirt roads” are unpaved roads made of soil, gravel, or packed earth instead of asphalt. They’re much rougher and can stress a vehicle’s suspension, tires, and traction more than pavement.

“Off roady” refers to driving on surfaces outside normal paved roads, often including dirt, gravel, ruts, and uneven terrain. It’s used here to describe a route that required more suspension travel and traction than typical street driving.

“Power wheels” here likely refers to electrically driven wheels or wheel motors used for propulsion or mobility in the vehicle setup. The key point is that the vehicle’s movement depends on electrical power, tying it to the battery charging issues they mention.

A “pedal assisted e-bike” is an electric bicycle that helps you when you pedal, using a motor and battery. The host is emphasizing that these bikes typically aren’t designed for jumping, even if they can move quickly.
