I found Curt makes a "universal" receiver that bolts on the rear of a trailer frame with 350# tongue weight rating, perfect for my 280# dual sport on a rack. Now just have to figure out the rear camera deal so I can keep an eye on it while traveling. The new trailer is camera ready but not sure what exactly that means. Looking at the wireless and wired cameras, would be nice to find one that uses a smart phone app and not a dedicated screen.
The DW and I worked on the Rage'n all weekend cleaning and emptying it; unbelievable how much stuff we had in that trailer. Hope we can not put it all back in the new one.
