We appreciate all the input, lots of good advice and things to think about.
Note: My disability affects me most in the heat and nothing heart related. The debilitating part is when I am up for periods of time I can become dizzy and weak and have to lie down until it passes. My wife is doing much better but hospitals/doctors are a concern we have taken into consideration. When I say full timing I guess I should clarify. We will be living full time but stationary for several weeks if not months at a time. We won't be on the road all the time, that is not our desire (much like djgarcia mentioned). Last year 3 months after my wife's surgery we spent 2 weeks tent camping in Colter Bay (Tetons) and fell in love with the peacefulness. I am not so naive as to think there won't be issues as I have read horror stories from truck failure to RV's that were constantly in the shop.
Everything posted has been a tremendous help and will be taken into consideration as we make our plans. We will form a fallback plan for sure. dahkota thanks for the info on Escapees, we will definitely be reaching out to them.
Just for everyone's info I am 48 and my wife is 47.
Thanks again and keep it coming...
