Here's wishing you well on your recovery! I haven't had any major health issues, but my sister did have a stroke and has had to deal with the aftermath. All I would say is that you will have to see what,if any, physical limitations you have once you are recovered. Then you will have to see how well you can handle the physical work required for hitching/unhitching a travel trailer, backing it into campsites and driving down the road. If you don't feel comfortable doing those things, then explore what RV options will work for you. A smaller self-contained class C or B could eliminate any hitching and towing of a trailer or towed car and a single unit is easier to back into a camp site. Or a smaller class A with a towed vehicle could be slightly easier depending on the type of tow bar used, auxiliary braking system and tow vehicle.
More importantly, just make adjustments in your RV traveling so you can continue to enjoy the RV lifestyle.
Best wishes and I hope you are on the road soon!
