Scientific study: People with problems report them on line 93.57% of the time; people with no problems report 4.72% of the time. Actually I have no idea of the %s other than to be sure that we hear significantly more from people with problems. I have used Reese/Drawtite WD hitches for 20 years without one single problem. A year ago I switched to Reese for a fifth wheel hitch. Reese support went beyond the call of duty to get my hitch height problem fixed. I ended up with their elite hitch which is excellent, but made in China. You get more for your money from other brands, but no problems with Reese.
