So as I understand it now, the issue is that when hauling on a heavy duty trailer like I used, there is so little weight that the trailer suspension has very little give. Then you strap the airplane down and its suspension now has no give either. On top of that, with the wings folded they introduce a bending moment into the aft fuselage over what the fuselage by itself would have. Throw all of this together in a pot and add a bumpy road and you have a bent fuselage because the bumps are transmitted basically directly from the road to the fuselage with no suspension to absorb in between.

After it happened I did a bunch of reading and those that trailer successfully have trailers with soft suspensions and many support the tail a bit forward of the tailwheel at the cross tube in the fuse, both of which would help the loads overwhelming the fuselage.

I'll probably make an extended tongue for my 1200 pound capacity utility trailer and use it in the future.
