Hitch with built-in TW Scale

Agree with Barney...the WD spring bar forces will add to the dead weight...unless the strain gauge setup in the ball assembly knows the difference between dead weight and spring forces (an angular vector from dead weight vector)

Think of standing on the tongue and pulling up on the spring bars. That then transfers whatever weight/force from your hands down to your feet...which is on top of the tongue...

Plus, strain gauge, meaning semiconductor and if as others say, hydraulic, so there is a transfer agent between the ball and strain gauge. Think both to manage the change in direction and to mute 'some' of the forces strain gauge. My guess is that there might be a hydraulic ratio to reduce the overall force on the semiconductor

Nifty, but I'd get a Sherline. Plus this is aluminum...not the kind of metal for my setup, but that is just me

That would not tell you how much weight is being transferred. All it would tell you is how much the pressure was when you coupled the trailer and then how much it increased from drawing up the WD bars. Doing that puts the "squeeze" on the ball from the coupler and downward pull of the WD bars on the A frame.
You would need to make some more measurements on the vehicles to determine how much was transferred. :)

My public scales are 40 miles in either direction, and I have to deal with angry truck drivers wanting to beat me senseless for daring enter their domain, and idiot scale operators who can't figure out what to do when I say "private."

LOVE the concept regardless. My only question is should I get the 2" or the 2-1/2"? I often tow with an extension that reduces my 2-1/2" receiver to 2".

Likely uses a load cell.

I have one of these, and they are great. However I do not tow my TT with it as it is not a weight distribution hitch. I asked the company about getting into WD, and they said they were "looking" into it.

If it's anything like the Sherline tongue weight scale, there's no spring--it operates hydraulically. If that's the case, there should be no movement.
