Today I had to go a dump with scales. My 94 f 350 & 6 x 14 loaded dump trailer with a 3 man crew and gear came to 18090 pounds. After dumping it came to 12000 pounds. I often load my JD 325 on the truck and trailer combo. JD is 9500 lb. I had no idea i was that heavy. Guys becareful laoding your trucks.
