Hotshot Bed Guide: Choosing a Flatbed Body for Your Truck

The bed is where your trailer meets your truck. Swap the factory box for a hotshot bed and you get storage, an easier hookup and a working look, but you also change the truck's weight and the hitch the whole load hangs on. This guide covers the bed options, what makers publish, how a new body changes payload, and what to get on the quote before you buy.

Hotshot bed options

What makers publish (checked October 2026)

• PJ Trailers Hotshot Body (GN): lengths of 8 ft 6 in, 9 ft 4 in and 11 ft 4 in, with a CURT rail system for gooseneck or 5th-wheel couplers and a 30,000 lb hauling capacity (PJ Trailers).
• PJ Trailers Aluminum Flat Deck Body (ALGB): lengths from 6 ft 6 in to 11 ft 1 in, with a 30,000 lb gooseneck hitch (PJ Trailers).
• CM Truck Beds HS Hotshot Body: lengths of 8 ft 6 in, 9 ft 4 in and 11 ft 4 in, built for CURT 30K gooseneck or 5th-wheel hitches, which CM says handle up to 30,000 lb (CM Truck Beds).

These are makers' own figures for one product each, in the order we checked them, not a ranking. Neither maker publishes body weights or prices on those pages, so get both from the dealer in writing.

One point that trips people up: a 30,000 lb hitch rating is the hitch's limit, not the truck's. Your truck's GCWR, GVWR and rear axle rating still decide what you can pull. The best hot shot truck guide covers those.

Fit: length and cab-to-axle

Bed lengths are sized to the truck's cab-to-axle measurement, the distance from the back of the cab to the center of the rear axle. Pickups and chassis cabs come with different cab-to-axle lengths, which is why makers list several body lengths. The body's fit chart tells you which one matches your truck; the wrong length moves the gooseneck ball off its intended spot over the axle.

Ball position matters because it decides where pin weight lands. Ford's 2026 towing guide sizes gooseneck king pin weight at about 15% of the loaded trailer weight and describes the gooseneck load resting over the rear axle (Ford). The same guide warns that short pickup boxes leave less room between the cab and the trailer in tight turns; a flatbed body with the ball set correctly solves the same problem.

How a new bed changes payload

Every pound of bed, toolbox and headache rack comes off the truck's payload, and payload is where gooseneck pin weight has to fit.

Payload before and after a body swapEXAMPLE

Truck GVWR14,000 lb

Truck weight with factory box, driver, fuel, gear8,600 lb

Payload left5,400 lb

Body swap adds (new body minus factory box)+700 lb

Payload left after the swap4,700 lb

Pin weight, 15% of a 24,000 lb loaded trailer3,600 lb (still fits)

EXAMPLE weights only; makers don't publish body weights on the pages we checked. Weigh the truck on a certified scale before and after the swap. On a non-CDL setup the margin is usually smaller, so a lighter aluminum body can be the difference between taking a load and turning it down. Our hotshot weight limits guide walks through the full formula.

Headache rack and securement

Most hotshot beds come with a headache rack, and it does more than protect the cab. If you carry cargo on the truck's deck that rests against the front structure, federal securement rules treat that structure as part of the system: it must reach 4 feet above the deck or high enough to block the cargo, whichever is lower, and withstand a forward load of half the cargo weight if it's under 6 feet tall (49 CFR 393.114). Ask the body maker whether the rack is rated for that.

Look for tie-down points on the bed too: stake pockets, recessed D-rings or a rail with track, so straps, chains and binders can ride on the truck instead of the trailer deck.

Custom and DIY hotshot beds

A custom hotshot bed from a local fabricator can fit your work better than a catalog body: longer toolboxes, a chain rack, a spot for the spare. A DIY hotshot truck bed can save money too. The deck and boxes are fair game. The parts to buy rather than build:

1. The gooseneck hitch. Use a hitch rated for your trailer and installed to its maker's instructions. It's the one part holding the load to the truck.
2. Wiring and lights. Keep every factory light working and wire the trailer plug properly. A dead light is easy for an inspector to spot from the road.
3. The truck maker's upfit guidance. Drilling the frame in the wrong place can void warranty coverage. Check before you cut.

Keep receipts and the hitch's paperwork. Your insurer may ask, and so will the next buyer.

What to get on the quote

• Body model, material and length, and the body's weight
• Hitch maker, model and rating, and who installs it
• Headache rack type and whether it's rated as a front end structure
• Toolboxes, lights, trailer plug and wiring
• Install labor and how long the truck will be down
• Warranty on the body and on the install
