I did it without the boat because they need a dry weight, but the guy behind me with a rowboat on a trailer weighted it with it on there. They actually laughed at my trailer and said it was cute and the lightest thing they had weighed in a while, haha.Thanks, great info.
Did you need to remove your boat from the trailer to take it in, or can they inspect to their satisfaction with the boat sitting on top?
Also, get a weight from a WSP scale, they are free (I paid to use a CAT scale at a truck stop as well, and it was worthless for the documentation).
