The DEMCO Glide Ride was selected by the staff of NuWa Industries, manufacturer of the HitchHiker Champagne and HitchHiker Discover America product lines to be installed as standard factory equipment on all 2007 and subsequent models of NuWa fifth wheel trailers.
My 2007 HitchHiker DA came with the Demco pinbox as standard equipment. I have towed it a little more than 20,000 miles so far and I am impressed with the way the Demco eliminates the chucking motion so common with fifth wheel travel trailers.
I towed hundreds of fifth wheel and conventional travel trailers during three years and 400,000 miles pulling trailers commercially as an RV transporter from 2005 through 2007.
I can honestly say that none including some very high priced Travel Supremes, Tetons, Alfas, Holiday Ramblers, and numerous Keystone, Thor, Forest River, Cherokee, Weekend Warriers, and other lesser known brands, some with air bag kingpins, towed as smoothly as my own HH with a Demco hitch.
I you're looking for a good one at a discounted price, I happen to have a brand new take off Demco Glide Ride hitch for sale. It was removed from a new HitchHiker fifth wheel by my local dealer because the buyer owned a SWB pickup and needed an extended kingpin box.
