At this point, I would never consider a flat roofed trailer no matter who built it. I had a flat roofed one, now I have an arched one. No question which is better. When it's set up perfectly level, all water will run off. The flat roofed one had to be tilted just a little to get water off it.

Lance does make a nice trailer, but they are flat on top, which can result in pooling water. If the roof isn't sealed well, that can be an expensive problem, and has been reported on this forum more than once. I would still consider them though.
Oliver Travel Trailers should be on your list if you want something that's going to last. Spendy though.
