Thanks to everyone for the insight into not only installation,but the use of side cameras.
Little clarification. I bought the unit from stock at Camping World in Mesa. It had all the options except the outside kitchen and side cameras.
We didn't want the outside kitchen since it reduced the outside storage.
We are driving out from Cleveland to take delivery on Monday. We have our daughter near Mesa so there is a little logic for buying it out here.
I had also posted a request for info on spare tires and got great answers as well. Still on a fence whether to carry a tire only.
