Absolute crooks. They have a pretty nasty racket taking advantage of travelers in distress. They showed us metal flake in the oil they claimed to drain from the crank case. We opted to bring it home. Oddly enough there was zero oil missing, just the oil the color you’d expect from a truck that had hauled an RV across four states. Oh, and after dodging calls for over a week, they had the unmitigated gall to charge storage fees. DO NOT USE THIS COMPANY!
