I have the sides framed up and skinned on this trailer I'm building. Got a frame made last night for the top: 1"x1"x1/8" square tube, 42" wide by 5-1/2 feet long, fairly simple perimeter frame with a single brace across the middle side to side.
Thinking of putting another 1x1" brace, centered, on top of the frame, running front to back. Then having the roof skin (16 gauge) bend over this "peak" to give a slight slope to the roof towards the edges. Will add additional bracing so the skin is supported just as if it was laying flat. Can see this would be a PITA trying to bevel the bracing correctly from the middle to the sides.
Not enough slant to prevent mounting a RTT later on. But, it would sure keep water from pooling on the top.
Thoughts? Yeah, or nay?
