OP, I don't think you are listening to the advice you are being given here. There is no question that RV's are "maintenance-intense" devices. The old saying "if you aren't fixing something today you are falling behind in your duties" has some validity.
Warantees, extended service agreements, and roadside service may or may not solve the issue at hand. The problem is making the arrangement for the service. Getting factory warranty work done on the road is often very difficult. What good is it for someone to agree to fix your loose hinge or broken tail light if they can't get it done for three weeks? In my experience, mobile techs are the fastest way to get repairs done -- some are good, some aren't, and finding one is often difficult.
I'm not much younger than you, but as I read your posts, you are setting yourself up for headaches. Just because you "want" an RV, doesn't make it a good idea. If I were in your shoes, I'd outfit a car with plenty of picnic and travel supplies, and motel it.
