Stuart, why would you come on asking for advice and act as though you already know it all?
Lou was only looking out for you, he had nothing to gain except not having to read about you dying.

Stack some short 2x10s or 12s of different lengths & drive up onto them.
About 4 high should do it. And lower the coach & let out the air before crawling under. Yeah, many people have scooted under for something but not to do what you are doing. Come on man. LOL
