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...
We went from a 41' Journey to our 43' Aspire and do not find it a lot more livable. Yes it has a huge bathroom and a 1/2 bath but the Journey was well suited to us. The BIG BUT is the ride and handling is just so much better with the tag, IFS and another 5 tons of weight!
