Bought a homebuilt trailer a couple of weeks ago, its a 5x10, sprung over with Bilstein shocks. I am having a rack built for it to hold my CVT, I have had a couple of local builders/welders look at it. One says to make it a permanent rack,sitting about 4 ft up above trailer rails so if I needed to haul a lawnmower or whatever, it would fit under it. The other option I was given was to make it removable, this way I would just have it mounted when I ran the tent and could remove it to haul whatever and it would only be about 2-3 ft off of the rails, easier access! Thoughts? Thanks!
