I don't think it was outside his skill set. The gas tank, bins, plumbing all got in the way. They would have had to add a lot of weight to the back end.
This may be the issue....not that it "can't" be done, but if the gas tank and propane plumbing are too close to the frame rails that he needs to weld to...then they must be removed to do the job safely.
So now installing the hitch is a huge job that requires significant dis-assembly and re-assembly of components....making the job more expensive than it is worth. This is likely why the PO put the hitch on the bumper to start with, because it was too difficult to weld to the frame rails. Anything "can" be done, the question is are you willing to pay for it?
Tommy, so many threads that caution adding a bike rack to the rear bumper and you're towing a car!!! Although the car doesn't have the same bounce as a bike rack does....glad you are safe!
Depending on your level of adventurousness, consider selling the car, then taking the MH back to home base and doing the pre-work necessary to install a frame hitch. You can work on it when you have time to work on it, not when it's a roadside disaster. You can get a mobile welder to come do the welding when you have removed the interfering parts.
