I currently have TT and truck and am fairly comfortable towing it. Hooking up and unhooking takes more time and effort than I would like as I age. I was talking with someone just Friday about driving a Class A. He has one that is 32-33 ft long and I was asking about test driving it, because I think I want to make the move to a Class A for security reasons as I travel alone. When I told him what I was driving and towing now, he told me that the MH would be an easy transition. He said he had driven trucks and trailers of various types, including semis and he felt like the Class A MH was much easier, even towing a vehicle.
OP, you say you won't drive if you stick with MH, let me encourage you to learn to drive. There are classes available from some dealerships and also a couple of companies that teach courses around the country. Even if you don't drive regularly, knowing you can in an emergency will help you feel better about traveling far away from home and family. I plan to take one at the point I buy a class A, just for the guidance and confidence. I had a truck driver instructor work with me for about an hour or two on backing my trailer and it sure helped my skills and confidence to go where I want.
