I go to government scales, when no agents. The scales are always ready to work.
I prepare my trailer normally charged for a trip.
Once there, in the parking adjescent, I prepare the trailer for it to be quick to detach and reattach the truck when I get on the scales. It's always at this moment that another traveler with a Bigfoot
happens also to weigh his trailer ...
With my Bigfoot
17' I have to use 2 trays, so I separate axle weight and tongue, which I note on the table to add them later. At this point you can quickly see if you are in the 10 to 15% recommended on the tongue of the trailer.
If I do not have the % recommended, but I have the total weight of the trailer, I move the charges to correct.
By having the total weight, then I can go home with a home balance, as indicated in the document "Etrailer".
