I am a bit plump but my rig is not even close to overweight. Running a 1999 F550 with 19K GVWR. Truck is 8900 LBS. 96 Caribou plate says 3600 lbs. Ya right. losded 5K lbs is closer. My self and a couple of dogs not even close to overweight. Hauling my 6x14 trailer with Rhino no problem. I bought the F550 so I could stop calculating weights. My current rig would have been overweight with my F350.
