How exciting!!
Have a great trip!
Be sure to check the side view cameras. Ours were reversed!! Run the cab air. We had no coolant. Don't forget the front running lights on the roof. Ours were not sealed well from the factory. Also need to check all sealant on roof. We had some gaps!
Our awning power wiring cable was not secured under the coach. It lay on the drive shaft and that eventually wore through some of the wires in the cable. We didn't know it until the awning quit working on our first trip.
Be sure to open up your couch, if yours has one. Ours had a tear which you couldn't see until it was open. We got a new couch!
Check all your tire valve extensions. There have been a bunch of duds, including Thor replacements, that couldn't read pressures or add air. Ours were replaced at a truck center under warranty.
Hope you enjoy yours as much as we do ours!!
