I dang sure wouldn't have the truck even close during auto level. All is good till the system has a brain fart and the fifth wheel crushes your truck bed. It's happened to several. Just use shore power as others mentioned, that's what we did. Oddly enough, I didn't care for the leveling systems, at least on the towable. Several reasons I won't go into. I'll probably never own another after having HWH, Big Foot, LCI etc. Had them all on different rigs. Will spend my money on modifications instead.
