I like mine a lot, too! One of the plusses is the fact you don't need a 'key' for the hitch pin, just the rails on the hitch do the turning...which means you can hookup and tow any 5th wheel with a king pin . Some kingpins require an adapter on the hitch's head, but it will still hook up with out a key.
Just had mine since spring and have about 5,000 miles on it.
It is heavy duty :) I bought a hoist from Harbor Freight that I put in the garage rafters to lift it out with.
Have the 18k HJ autoslide, pull a 15 k fiver,over 55000 miles on it. Just rebuilt the top part of the head,excellent hitch,very heavy.Mine has the slide bar, the new ones have the jaw type clamp.Very good service from Demco.
