If not salemen showing the operation of RV, who does?
When we bought our RV, salesperson, did nothing more than pulled the resources together. Service Manager and Financial Manager together. Service manager for the options on the rig and the Finance guy for "The Sale".
After the sale, at time of picking up the unit, they have a Tech to show us the "Ins and Outs" of the trailer. The Tech DIDN'T KNOW SQUAT! He didn't know how to turn On the Refrigerator, didn't know where the breaker panel was, no idea of the Water Heater system, but he did know how to turn on and off the lights and operate the slides.
Back to the OP, I use auto level every time and never has my tire(s) been off the ground. I will, every once in a while, double check the level with a app on my phone.
