A lot depends on the juristiction of the owner of the scales in question. Apparently, in Oregon, the government owned scales are left on when unattended, and people there are free to use them unsupervised.
Here in California, the government scales are only for the Big Rigs to use, and are usually manned 24/7. Private campers are discouraged from approaching them.
Here, certain private/for profit companies operate "Public Scales" and are listed as Scales, Public Weighers
th the yellow pages. They charge a nominal fee ($5 - $10) to print you out a weight ticket. They are usually side businesses of Moving & Storage companies, or Recycling Buy-back companies.
way to weigh
your egg is to park it, with the tires
AND hitch jack on the scale, and completely unhitch it from your tow vehicle, which is off the scale. That will be your Gross
trailer weight. Then, re-hitch your tow vehicle, and park with the tow vehicle's wheels off the scale and the trailer's wheels on the scale. That will be your Axle
trailer weight. Subtract your Axle
weight from your Gross
weight to get your Hitch
My gross weight was 2620 pounds, and my axle weight was 2420 pounds, which made my hitch weight 200 pounds.
