Congratulations on the new rig. When we did our shakedown cruise, we did return it to the dealer for every little detail. It meant an hour drive through Phoenix but it was important to us that all issues be documented. At some point, the RV industry needs to recognize the shoddy workmanship in some of their rigs. We have an Open Range Roamer which we love but it had loose trim, a stained sink that we couldn't get clean and other 'little' things we could have fixed ourselves. The dealer fixed it all and now we are road ready. Happy travels to you!
BTW, our AC didn't shut off either until the dealer showed us the on, off, auto setting on the thermostat. Once we set it to auto, problem solved! Mattress - RV mattress are horrible! We sold our and put our Select Comfort mattress in our rig.
