I would love to do this. My wife...not so much. All she sees are maintenance troubles on the road and the horrors of “camping”. She is not to be “inconvenienced”. LOL.
We met many couples like you who were doing a week end camping trip but would not consider a longer trip. We were full time with no home base. But the main thing is that you have to be comfortable with that one other person. When I suggested it, my wife did her “happy” dance. It turns out we both loved being on the road but after a time we got too old to want to do all the basic camping things. So I understand completely. That’s when we moved into a condo community and sold the RV. Yes, sometimes I miss it, but it really was getting to be too much of a chore to hook up and go. We discovered this after living for 4 years in our condo and realizing that we only took the RV out one time.
