I used one of these with the omni. The Roadmaster attachment page is correct, 3" maximum. It's easy to figure though. Measure the height of the base plate attachments on the toad. Measure the receiver hight on the motorhome with the motorhome at travel height. That means level surface, not on jacks, suspension at ride height if air type suspension and loaded for travel. Get the Hi-low hitch receiver adaptor that gets the bar near level. Adaptors ain't cheap but doing it right isn't either. Pic is what I used.
