I use a B&W companion, mine's almost 3 years old. Very soon after I installed it I came to realize that the 4 rubber pads were very inadequate so I replaced them with 1/4 inch thick reinforced rubber belting held in place with just 2 ea 3/16 bolts and they have held up excellent. One thing I didn't like about the companion was B&W's installation method, I know they designed it... I did try to talk with B&W over this and they became very defensive to say the least. After asking around I settled on a different installation method which I have used from after the first month or so. With the Lippert's recent approval of the Reese goose pin box and the possible use of no safety chains many may drop the use of the companion altogether. I definitely see the flex and also have a couple of creases in my bed at the rear of the hitch feet.
