2660lbs!

I was really surprised, I went to drop a load of metal to the scrapyard and weighed it before and after. This is with no driver and almost empty tank. On the liscence papers it says 1355kg which is 2981lbs. I do have a wooden bed which is probably lighter than the original but I have p/s, rear disc swap, front tacoma brake swap, 31'' tires on 15x8 rims. Has anybody here weighed their truck?
