I'll admit that's pretty cool. But my God... $300 - $500 for a hitch that can't even take WDH?!? That's awful high.
I'll have to dig into this, since if they had a WDH variant at similar pricing, that'd actually be something I might use. But as it stands there, I can do the same with a $15 bathroom scale, a piece of timber, and a jack stand... all of which most of us already have. That Weigh Safe hitch definitely saves time, so it has a place, I'm just not sure I'd want to spend $500 to save 10 minutes on those rare occasions my hitch weight is actually high enough that it warrants weighing.
There's also jack-stands topped with trailer balls and integrated scales on Amazon, which if I recall mostly ran $50 - $100. Set them at desired truck ball height, drop trailer onto them, voila! Not as convenient as the Weigh Hitch, but definitely much cheaper.
I just checked 2" x 8" size, and it's
only $364, but there's no 1-7/8" ball option. Some of my trailers are 1-7/8", as that was a very common size in the 1970's and 1980's, and I tow a lot of vintage boats/trailers. I think the hitch I use now for those boats cost like $20 - $30, and the ball was probably another $20... so $40-$50.
