Thanks for the tips guys

Appreciat the logic on the 19.5's and do see the benefits but I'm going t do some checking in this part of the world as too availability.

Last time a friend tried to get 19.5's for his older motorhome up here he had a heck of a time finding them, which is why I wasn't going that dirction.

But before I make a final decision I will re check...maybe times have changed.
