Take the next trip in just the truck or a car, make sure it's for a week or two. See if he enjoys
. Checking in and out every day
. Carrying the bags in and out every day
. Having to eat from restaurants all of the time
. Having to load and unload the vehicle for every trip instead of using the trailer already packed
. Forgetting to pack something
. What's he going to think if the vehicle breaks down?
. Getting a lousy hotel room with no view
. Not being able to sit outside and enjoy the sun or evening cool
. Gets tired or paying triple for a hotel room vs an RV spot
. ?
After a couple of car trips he may well want to go back to the trailer. Don't sell it yet.
