Bigchevyhitch does look beefy but it does not meet my requirements to be DOT legal in case if something happens. I can tell it has bird shit weld all over it, definitely welded by a rookie. My factory hitch has pulled over 15k numerous times without a problem and did over 20k, maybe 30k when I was pulling my trailer from AZ until the accident happened in PA. The towing company claimed it was definitely over 25k lbs and couldn't believe I towed that thing 2k miles until my tire failed. The tire failed causing me to do a double jack knife against the trailer while the trailer was pushing my truck into the median on the freeway, I thought I was going to flip over. The factory hitch held no problem until the trailer hitch ripped off the pintle frame and mangled my factory hitch. Luckily everyone was okay, especially my pets that were in the bed inside the camper shell. The camper shell was really beefy which saved my pets.
So I rather trust something that is DOT legal in case if something happens. Better safe than sorry. Curt looks like the winner in this case.
