Thanks everybody! I will figure out a way to get weighed. The gravel yard 20 miles away is my only option so hopefully they won't mind. I looked up the T@B and T@G site, I have no idea what that stands for but it seems to be for a specific brand of trailers. I'll join and ask anyway. I'll try dropping a little tire pressure and see if that helps.
And I am located about 5 miles outside the teaming metropolis of Albion, CA, population 299. :-) Nearest official weigh scale of any type will be at least 50-75 miles away over hill and dale.
Thanks again for all the replies, this seems like a friendly place.
