If that's the case, you wouldn't be able to do the measurements the way I suggested, since you have to have the trailer connected to get it up on to the scale.
So, you could weigh the combination together (with the spring bars disconnected before getting on the scale - you're only going a tiny distance). Then, drive off, drop the trailer and get back on the first two scales with just the truck.
Then, your tongue weight is the result of subtracting the uncoupled truck weight from the coupled truck's weight.
When I did this, I was not told anything about the scales not resetting. Maybe some do and some don't?
