Spring brings on the yard clean up frenzy in me. I had done some home improvement work on my house. Broke up a brick front stoop and install a new 1/4 basement under the house. To make a long story short. I had all this cement and brick debris to haul away. So I threw it all into the bed of the truck til it was falling out of the sides. Put extra air in the tires. The springs were about 3/4 of the way down so I figured I had maybe 2,000 Lbs. The truck drove just fine and it really didn't feel that bad stoping. When I hit the scale at the dump, the lady behind the window went cross eyed. She said " DO YOU KNOW HOW HEAVY YOU ARE!" I weight in at 12,660 LBS. Drove out 7,200 empty with a smile.
