I recently purchased a single axle 6‘ x 12‘ enclosed cargo trailer. I have an ATV and a snowmobile that I use for icefishing that I would plan to haul in the trailer (one at a time). My question is if anybody has set up a trailer like this with some type of rack that would sit above the four wheeler or ATV and allow for me to put portables on it. i’m guessing some sheets of plywood that would run for most of the length of the trailer, but you’d have to have some supports built in there as well as some thing on the sides of the trailer to rest those supports and plywood on. The goal would be to haul an ATV or snowmobile, and one to two portables on a second level within the trailer. Anybody done anything like this?
