Lets say I'm on medicare and so far I still doing fine getting into and out of both the camper and the bed in the camper. I'm larger girth and do not have knee problems but I sure have seen smaller thin people that have had a lot of knee problems and replacements. My problem is a bad shoulder from a motorcycle accident I had in my 30s that is now haunting me. So at this time I don't see use leaving the camper but as we all know things can happen suddenly that change everything.
