If you go this route, make sure you don't get the XL. It'll take up almost the whole floor.
Watch out on the military version. See those corner braces and the matching gap in the canvas along the side rail. I think that will interfere with the desired length of the shortened canvas. In order for the side organizers to work out, you have to trim the same amount from each end of the canvas. The cot is very sturdy without the corner bracing.
Good advice. Simpler may be better. I'll need to do some measuring when I get the trailer all set up.
