Right on vike! I used to train a jetski behind the boat behind the 30' class a . 71' long total, all over Montana ,Wyo , Utah. Don't think I'll do that again. If you don't have to sleep a lot of people , slide in camper works well. Matter of fact , I am still am set up that way. Problem with the long vehicle is , backing up , getting fuel, pulling into the campground, unhook , hook up to put the boat in . Also up and down the mountain passes , that is another story.. Montana not too bad , Colorado , uh takes more time. If you don't have to go too far, I guess it wouldn't be too bad, more rv and also can bring the boat! I would also consider "panic braking" it will happen , someone will pull out in front of you.
