Just FYI, we full time in a 36'er (see signature). Our size is limited by access to our son's farmyard, takes 5 to 7 point turn to set up with the current coach, 40' would not make it. This is our third year in this 4 slide coach. Before this we lived in a 36 foot two slide Southwind with gas engine.
We have a lot more storage now and DW is more than happy to take her share of time behind the wheel, we switch every two hours. As I write we are both in the LR area with our computers on in our son's yard while they do schooling and work.
