I need a trailer and would like suggestions on what options are critical for RC, and in general. I think I've narrowed it down to a Look trailer; they have the ST, Element, and Vision. Do I need things like 16'' OC wall studs, one piece aluminum roof, screwless exterior, etc? Any other important features to consider? The plan is for a 5x8 with swinging rear door and a side door. Possibly wedge front with sloped top, or round front and round top.

ST (base model, incredibly reasonable)

Element (likely candidate, plywood sides, nice features)

Vision (possiblity, plywood sides, has screwless exterior, one piece aluminum roof, radial tires)
