Awesome comparison. Great technical info too. I'm trying to relate my much smaller, literally, decision on RV purchasing. We have a somewhat stationary 5th (switch between 2 locations annually). We will not be full time, but hope to really have some/many long retirement trips. I'd be interested on what your initial thoughts, pre-purchase on benefits of the change. Sounds like you had a wonderful experience in your A. And know you'll have the same with the new 5th!
