Resource center
Answers before you buy
Fitment guides, buying guides, manuals and a payload calculator. Free to use, no sign-up.
What size flatbed fits my truck?
Cab-to-axle sets bed length. As a rule of thumb from CM: 56–58" CA takes 8'6", 60" takes 9'4", 84" takes 11'4".
Flatbed or service body?
Open deck for hauling and towing, or locking storage for tools. Compare them side by side.
Choosing a truck toolbox
Underbody, crossover or chest: what fits your truck and what you carry.
Payload calculator
GVWR minus curb weight minus the upfit. Check it before you spec the body.
