Take her to an rv dealer and see if she likes other type of units better. I know with the tt we had that my wife enjoyed our trips, but she didn't enjoy the preparing and worrying bout the big trailer behind the camper. She was never one to be jumping at the bits to go somewhere and to mention dry camping. Shut our mouth!
But now with the motorhome sitting in the driveway, she loves it and looks or ward to going. Preparing is a lot easier and she doesn't worry about a trailer behind us or feel closed in one spot during the trip. And she is even talking and looking forward to dry camping.
