Trailer

A tape measure and a few minutes. Here is each measurement Build Your Ramp will ask you for, and exactly where to take it.

Front to back, that is the Deck Length, from the front usable deck edge to the rear usable deck edge. Across, that is the Deck Width, from one usable side edge to the other at the widest clear part.Keep the tape straight along the deck surface. Not the tongue or coupler, and not a diagonal.

Trailer cargo area lengthEnclosed trailers: with the rear doors fully closed, measure along the cargo floor from the inside of the rear doors to the inside front wall, or to where your loading area ends.The usable floor inside, not the trailer's outside length. Keep the tape straight along the floor.
