I am in the process of planning for my friend (he is a certified welder) to build me a trailer. Looking at a 7X16 open for now. I can't decide whether or not I want to go with solid 2' sides or mesh 4' sides. I was wondering if any of you have trailers with high sides if you have any type of gate assist. I have seen them on trailers with lower sides, but not on trailers with the high sides. If you could, please post where you got them or if you made them yourself. Thanks.
