It seems that the RV industry and the boat industry are such that if the owner can't take care of things they are destined to be disappointed. Both are hobbies that are best suited for handy folks willing to do-it-yourself. If you are dependent on dealer service your boat or RV will be in the shop more than you like.
Nothing wrong with that. A lot of hobbies are that way. That's why they are hobbies. It's just that some folks get into the hobby without proper preparation and find out it's more like a Robin Williams movie than they thought.
