The ONLY thing m wife dislikes about a 5th wheel is not being able to get up to use the restroom or make a sandwich while I drive. We've owned them all. TT's, 37' MH, class B+. She would actually prefer a 30' TT because of the head room in the bedroom area. But, she's says she fine with the 5th wheel, with the floorplan she loves. As for the rest of your questions....I see no real difference in anything driving a MH with a toad. Mileage is going to be about 12mpg towing. Better than a MH. Having a truck at home for a second vehicle is great too.
