I'm thinking on a plan to make my teardrop removable from the trailer, so I may use the trailer for other things. First, I would leave the teardrop on the trailer when not in use to prevent warping and damage.
The trailer I'm thinking of using is from Red Trailers http://www.redtrailers.com/ShowTrailer.asp?id=4
or this one from Harbor Freight

I would use 2X4 lumber as the frame (the 4" side facing out and 2X4 stringers (the 4" side facing up) using dowels and screws and possibly corner gussets to secure the bottom frame. The TD frame would ride outside the frame of the trailer. There I would either or both bolt the trailer through the sides hanging down or have angle iron constructed where I would bolt that to the wood, the iron would go up and turn 90# flush with the top of the frame and I would have welded a down peice that would slip into where the stake side would have gone. Any advice?
