I have the B&W Companion and with one leg and some back problems I can still get it in and out by my self. I use the plastic covered edge of the tailgate to tip and slide the base in and out. Works for me.
I replaced the pin box on my 5er with the Demco Ride-Glide. After a couple of hours with out the DW commenting on the jerking I knew I had made the right move.
A guy in the park here just bought a new dually and had a hitch installed. Even though it's rated higher than my 18,000 lb B&W he commented on how much thicker the jaws were on my hitch.
