I saw their seminar last year at the HOC Tucson Rodeo Rally with a demo using an RV refrigerator cooling unit.
Pretty interesting stuff (and I have some photos of the demonstration I'll dig out later).
Kind of explains why we could never keep ice creme cold in the fridge of our last trailer, a 2013 Heartland Trail Runner with the rear kitchen:
The fridge was on the back wall instead of a side wall, so when we parked it out along the curb in front of the house for a day or two when getting ready or coming back from a campout, I never worried about leveling it side-to-side (although I did always level it front to back).
I now know better about running the fridge when the trailer is not level.
Our Prowler has the fridge on the door side wall so the concern here in Colorado is driving up steep mountain grades:
On the interstate highways I usually don't shut the gas off, but on those slow steep climbs I'll shut it off.

Dan, remember that John has a Chevy so it probably takes him longer....LOL
Pretty funny stuff!
However, that 6.0L gas engine with the 4.10 rear end will kick those fast & furious wanna'bees butts when the light turns green!
