Those sides came 4' across. I have been cutting them and the piece I cut is being bolted to the backside of that lower half to reinforce. My old trailer had 3' foot sides and was perfect height for hand loading and machine loading. I plan to haul the toolcat with this trailer. It only dumps 7'. Eventually I will get a small skid to haul but the Toolcat is already here for the ranch.
