Hang in there biker. We have some folks don't believe in towing doubles (2 trailers). In my state we actually tow RV triples (3 trailers) mostly in the summer (5th wheel trailer/ski boat/PWC trailer ....or load of ATVs/bikes.)
I double towed with a 26' 5th wheel trailer and a 3400 bass boat for over eight years. Hitch weight was 220 lbs. I also tow agriculture doubles.
I had a weld shop custom fab the hitch to the trailers main frame rails/crossmembers all welded. The shop used 1/4 wall 4" square tubing along side the main rails including the first axle and across the rear....and 3" square tubing for cross members.
400-500 lbs is a huge amount of weight way out behind the trailers axles unlike our trucks. Apples vs oranges.
Some Rv trailers main frame rails can be very weak as the units sidewalls/roof give the unit overall strength unlike a truck or a flat bed trailer where the heavy main frame rails/16" on center cross members are its strength.
As I said rv trailers main frame rails are pretty gimpy on some smaller trailers so do your home work on bracing the frame to carry more weight so as not to pull the sidewalls loose from the units floor. I always have my fab shop include the rails including the axles. Good luck on your new project
