The most important part of your post is the "itch to drop everything and change my life". I would focus and explore that part more before deciding on what type of rig to buy. We are all in different situations and it's often very difficult to plan anything. I have read posts about people who had to stop driving because of health issues or they dont have sustainable income sources etc.
I have only been a snowbird for 2 years and dang if I myself haven't got a health issue already. It's not terrible but but it may change what we had planned to do.
So when looking at rigs I chose a used fifth wheel and a new truck. I figured if we had trouble with the truck we could still have the 5er in a park and not lose our home. If we have trouble with the 5er or change it we can still drive the truck. If you get a motor home will you also have a towed and the resources to put you in a motel if repairs are needed on the MH? Will you have the resources for major repairs. It's not always as cheap to travel as some think.
I have seen a lot of rigs and talked to several people who end up parked in an rv park because of issues they didn't expect. If it happens to me I'll be parking a non motorized cheap used fifth wheel in a park and just drive the truck or get a new car.
Nothing wrong with getting a motor home but study the big picture before deciding. You may even go with a new or decent truck and a cheap TT. I would surely have a large chunk of money set aside if riding off with older motorized equipment. I would also be the do it yourself type.
