What does my load weigh & how do you read the stickers

I have been driving local, 60 mile round trip. I just had my first heavy load and want to know how heavy it was. So I weighed it. it was 70,460 (steer 10,960, drive 28,020, trailer 31,480). Now if I knew what the truck weighed I would know what my load weighed. It is a new Freightliner day cab and a 48' trailer with a roll door. Any idea what I weigh empty with 3/4 tank fuel? If I weight myself empty I have to pay for it and I return it to the rental company Monday.

I thought there would be a sticker on the truck with the empty weight but I couldn't find it. I found a sticker that has GAWR and GVWR. What do those mean? On the trailer GVWR is 68,000 and GAWR says 2 @ 20,000.

 

Since I am local warehouse to store I don't have a BOL. They guessed at the weight of a pallet full of floor tiles at 2,000.
