We are getting ready to make the jump from TT to a diesel pusher. Besides the 3rd axle are you gaining that much more room with a 45' vs 40'. We will have a toad, spend part of the winters in the warm...
Now that I've had a tag axle coach, no way would I go back to a 40' none tag. The improved handling plus the 9,000 CCC makes buying two more tires a none issue. X2 on Dennis's comments and multiple 600 mile days are easy...even on windy days. We stay mainly in USFS CGs without problems but do not show up Friday hoping to find a spot big enough. That's right, we do not make reservations. I would not buy a new coach and the one in the link above is way over priced.
