Kat scale user here. I always feel funny standing in line with the big rigs with my little setup. Feel like a little kid talking to the 10' high speaker on the scale.

When I was setting up both my travel and car enclosed trailer I used the scales several times to play with the bar settings to get what I wanted on my axles. Only way to know you are setup properly.

Also when you buy a trailer in NJ that does not have a weight posted on the previous title, they make you weigh the trailer empty so they can determine the registration cost.
