An awful lot of enclosed trailers, including my own, have flat roofs. If
you think about it, the odds of the trailer ever being parked level are
pretty slim, and water sheds off just fine. they also are typically one
piece aluminium for the top - no seams.

Possibly a gentle bend to some rebar would work with a straight leg on
each end to fit down into a couple of screweyes or eyebolts.

First a giant no to Ken's concept. Nobody would consider trying to
drill and rivet rebar for a roof arch. It is absolutly the worst
structural shape for the application. Roof arches are usually done on
a three wheel ring roller and just a little crown is put in. Brian has
a very interesting piece of aluminum on top of his trailer. 8' x 20'
with no seams. I think he needs to look again because this would be
tough to buy. I have seen the arch tubing bandsawed in a notched
configuration and then bent. Looked absolutely awful and I walked
away from that trailer builder figuring if he didn't know what he was
doing in the roof area I sure didn't want his frame. I don't know
where to send you for bending square tubing but be careful about
listening to bad advice on RCM. Leigh@MarMachine
Gotta reply - nobody said anything about drilling and riveting
anything - or for that matter even what the roof was going to be made
of. I only mentioned the rebar as a shaping medium to get the gentle
crown needed to make the appearance right. The rebar can be used
under a tarp, plywood, sheet steel, sheet aluminum or whatever. The
simplicity of it is that the rebar only has to be slightly bent to
provide the shape and the ends of the rebar can be mounted inside the
trailer in any fashion that will support the bows vertically.
