To be short and sweet, Not sure I would trust this for it's 22000 lbs rating. It claims it can take that weight, but it is not certified or marked. Also, in one section of the information for this product it says 22,000 lbs, but in another it shows 2,2000 (It's probably just a type-oh, but...) This definitely seems heavy duty enough, I will have no problem feeling fine towing anything within 5000-10,000 lbs of gross weight, and I'd keep the hitch weight at no more than half also, but I would stop there.I have a 10,000 lbs tiny house that I need to move on my property. This is the main reason I got this. The tiny house is right at the top weight of 10,000 lbs, but it only has a 1000 lbs hitch weight. I only have to move it 1/4 mile on private property, so I feel pretty good with that.It would be really nice if it was DOT approved or at least had some certification one the load. Not a big deal, but it would also be nice if the ball sizes were stamped on the balls (minor) but...
