Three areas I have experience with since purchasing my Vegas this past May:
1. Safety Recall 15V-530 Advisory RC000103 Heater/AC for the 2016 Vegas Model.
2. Crawl under the unit and have the mechanic verify that the rubber transmission cable is not resting on the exhaust system (see thread 350 Can't shift out of drive this forum).
2. Check the brand on the house batteries. I am having a Warranty problem with Harris Batteries and the WFCO WF-8900 Converter/charger used on my 2016 Vegas on the E350 Chassis.
