I've been wondering about doing the same thing. I'm in Missouri, and I need to check and see what the laws are first I guess. I'd like to tow my lightweight aluminum 8x10 ATV trailer behind the "new to me" 19ft TT that I just picked up. The travel trailer weights it at around 3,600lbs empty, and my ATV trailer with two sport ATV's comes in around at 1,000lbs. The tongue weight on the ATV trailer is around 100lbs....so I don't think it's going to unload the front of the travel trailer very much.
If legal, would a setup like this be ok to two?
