Are we talking open or enclosed?
Your only two considerations would be tongue-weight and GVWR. The tongue-weight issue could be addressed very nicely with a "Trailer-Toad" (
www.trailertoad.com). Most of the open trailers that are able to handle the weight you're planning on hauling are configured as fifth-wheel or goose-neck models, but Kaufman Trailers in North Carolina has both a 14000 and 18000 lb-rated 34 footer available, and they custom-make each of their units. I've been towing a Kaufman since 2010 and I'm very happy with mine. (
