Both our ours went with us right up until college. They probably would have went longer but job changes and working out of town resulted in time off spent at home rather than camping and the camper was out of town as I used that to live in temporarily until we got relocated back to where we are now. Now that we live on the coast on the waterfront they spend as much time as possible with us when they are off from work. We are still a very close family.
The last year or so they would take turns bringing a friend along, and we also had a tent and they chose to stay in that at night.
