[quote author=]For the life of me I can't understand while Roadmaster didn't engineer their system for a more typical ride height. As I recall, most pick up trucks have a hitch height of about 16".

I don't know that there is a "typical" situation, Gil. Ride height and hitch height are two different things. Like other mfrs., Roadmaster designs the mounting brackets specific to the vehicle being towed. But coaches can have different hitch heights, the only control over which Roadmaster has is the use of Hi-Low hitches to raise or lower that height. Our Explorer was a bit higher than our '06 Monterey's hitch, and the towbar always had a slight slope to it. Our coach regularly drags bottom back there, for complex reasons I won't get into here, but suffice it to say the hitch is relatively low.
I finally had Roadmaster, at their Vancouver, WA, main facility, add the appropriate Hi-Low, Quiet Hitch, and a Rollaway to my setup. They know more about what they're doing than others I've been to, and charge little if anything for their time. The year before, I had them reconfigure (sans coach) the toad's front hitch setup, esp. the air, breakaway, and electric fittings, because Camping World's initial installation left much to be desired. Roadmaster charged nothing for their tech's time. I can't say enough positive things about Roadmaster's people, at least in the Portland/Vancouver facilities.
My point is that coaches are different and toads are different; the owner has to adapt his setup accordingly, from a low 2WD small car to Hummers. A towbar mfr. can only do so much up to that point, but they can and do offer adaptive devices per application. A good installer, like Roadmaster Vancouver, and a knowledgeable owner work together for the optimal setup.
