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.

Process

How we work

The same four steps for one pickup or a dealer order of twenty.

  1. 1. Spec

    Send the chassis (year, make, model, cab, cab-to-axle, GVWR) and what the truck has to do. We confirm fitment before we quote.

  2. 2. Quote

    You get a written quote for one unit or the whole order. Repeat orders can reuse the same spec.

  3. 3. Build

    Install, fabrication, wiring and lighting happen at our Commerce City shop.

  4. 4. Deliver

    We tell you when it's ready and set up pickup or drop-off.
