opinions on hanging a dirtbike off the back?
This is no problem for a class A motorhome, I see it all the time. But what about a hitch receiver on back a 10000+gvw fifth wheel with a bike lift and say 350-400 lbs of dirtbike? Gotta consider ...

Just for reference, my Jayco factory installed Class 3 receiver is rated to 3,000 lbs towing or 300 lbs tongue weight. So if going for aftermarket, it would be advisable to find a reputable hitch shop that can advise. Plus a call to Jayco about proper attachment and how big you can go without risking frame issues. I'd guess you need to go to Class 4, at least.
Ditto in spades for the actual carrier. For bicycles there are almost no models where the mfg. doesn't specifically state that they are not to be used for "trailers" (only 2 brands I am aware of, and the specific models are very limited). The added length rear of the axles means a huge increase in the pounding the carrier and hitch assembly will be subject to. And, you have to extend even further back than "normal" to clear the bumper. 400# of dirt bike is many, many times more load than 100# of bicycles because of that. So you'll want far more strength for everything than you might otherwise assume.
You might be better off getting a mini-trailer for it, and making sure you can double tow.....
