Truck makers name their beds in round numbers, but the real floor length can be several inches different. Ford's "5.5-foot" F-150 box is actually 67.1 inches at the floor, closer to 5 feet 7 inches. Before you pick a camper, take three quick measurements.

What to measure

  • Floor length: with the tailgate closed, measure along the floor from the front wall of the bed (the bulkhead) to the inside of the tailgate.
  • Width between the wheel wells: measure straight across between the two wheel wells. This is the narrowest point, and it's the number that matters for a camper.
  • Inside height: measure from the floor to the top of the bed rail.

Before you measure

  • Take out any plastic slip-in bed liner. It has to come out before a camper goes in anyway. Spray-in liners can stay.
  • Measure at the floor, not along the top of the rails. Many beds are a little longer at the top.
  • Write down your truck's year, cab style and bed name too. It helps us double-check.

These are Ford's published figures for recent model years. Older trucks and other makes differ, so always measure your own bed.

Which camper fits?

  • 6- to 6.5-foot beds take our short-bed campers: the Panther and Ocelot on full-size trucks, or the Bobcat on mid-size trucks.
  • 8-foot beds take our long-bed campers: the Cougar and Puma, or the Lynx on mid-size trucks.
  • Shorter or in-between beds, like the 5.5-foot F-150 or the 6.75-foot Super Duty: give us a call. We build custom campers and can talk through what will work.
