Truck Camper Glossary

Every term you need to know when shopping for, comparing, or living in a truck bed camper — from payload basics to electrical systems.

Weight & Payload

Payload Capacity

The maximum weight your truck can carry in the bed and cab, calculated by subtracting curb weight from GVWR.

GVWR (Gross Vehicle Weight Rating)

The maximum allowable total weight of your truck when fully loaded, set by the manufacturer and printed on your door-jamb sticker.

Curb Weight

The weight of your truck as it sits on the dealer lot — with a full tank of gas, all factory fluids, and standard equipment, but no passengers, cargo, or aftermarket accessories.

Dry Weight

The weight of a truck camper as it leaves the factory — no water in the tanks, no propane, no gear, no batteries beyond what's included.

Wet Weight

The weight of a truck camper with full fresh water tanks, full propane tanks, and a charged battery bank — but typically without personal gear.

Tongue Weight

The downward force that a truck camper exerts on the bed of the truck, which is essentially the camper's full loaded weight minus any overhang that extends behind the tailgate.

GCWR (Gross Combined Weight Rating)

The maximum allowable total weight of your truck plus anything it's towing — relevant if you're pulling a boat, trailer, or toy hauler behind your camper-loaded truck.

Pin Weight

The weight transferred to the truck at the camper's mounting or tie-down points.

Camper Types

Slide-In Camper

The most common type of truck bed camper — a self-contained unit that slides into the truck bed and is secured with tie-downs or turnbuckles.

Pop-Up Truck Camper

A truck camper with a collapsible roof section — either soft-sided (canvas/fabric) or hard-sided (fiberglass/aluminum panels).

Hard-Side Truck Camper

A truck camper with fixed, rigid walls that don't collapse for travel.

Shell / Canopy Camper

A lightweight topper or cap that covers the truck bed, creating an enclosed sleeping and storage space.

Wedge Camper

A low-profile truck camper with an aerodynamic shape that angles from a taller rear wall down toward the cab.

Flatbed Camper

A truck camper designed to mount on a flatbed or utility bed rather than a standard pickup bed.

Chassis-Mount Camper

A camper that bolts directly to the truck's frame rails rather than sitting in the bed.

Slide-Out

An expandable section of a camper that slides outward when parked to increase interior living space.

Cabover

The section of a truck camper that extends forward over the truck's cab, creating an elevated sleeping area.

Construction & Features

Aluminum Framing

A camper construction method using aluminum structural members instead of traditional wood studs.

Composite Panels

Laminated wall, floor, and roof construction that bonds an insulation core (typically EPS or XPS foam) between fiberglass, aluminum, or Azdel skins.

A designation indicating a camper is designed for cold-weather use, typically meaning enclosed and heated holding tanks, upgraded insulation (R-7+), thermal-pane windows, a furnace rated for below-freezing temperatures, and insulated plumbing.

Thermal Pane Windows

Double-pane insulated windows with an air gap between two layers of glass or acrylic.

Basement Storage

Storage compartments built into the area below the camper's main floor, accessible from exterior doors.

Shore Power

An external AC electrical hookup (typically a 30-amp plug) that connects your camper to campground or household power.

Boondocking / Dry Camping

Camping without any hookups — no shore power, no water, no sewer connections.

Turnbuckle Tie-Downs

The hardware system that secures a slide-in truck camper to the truck bed using anchor points on the truck frame and attachment brackets on the camper.

Happijac System

A brand-name electric jack and tie-down system (now owned by Lippert) that uses motorized corner jacks to load/unload the camper and integrated tie-downs to secure it.

Overcab

The portion of a truck camper that extends forward over the truck cab, typically housing the primary sleeping area (bed).

Truck Compatibility
