Sometimes a change is as good as a rest, and we can all experience at some point or another having too much of any one good thing! The newness and anticipation has long worn off, and for sure you would have seen untold changes over that number of years from when you first started out. I know in the 15 years we've been RVing, we have for sure and our biggest pet peeves are the "over governing, more licensing etc" of things we enjoyed doing. We were blown away by the change of impression this year in visiting many towns on a Washington/Oregon/Northern California trip, compared to how much we loved it some 12 years prior!
Rather than risk the loss of selling it all up, can you not just park all up for a while and try different forms of travel/areas/places - countries even. Just to change it up for a bit or even mix it up for a bit.
Pros and Cons lists always help me when considering making a major change decision in our lives = Just a thought, and for sure can relate at times.
