Well after reading your replys, I should have given a little more info. Sorry I was heading to bed after working all night and then a trip to the Gravel pit.Stupid or not, I know the truck has dry weight of 6300lbs, and when I filled up the bed, the loader guy stopped and asked how much more. I told him to add more. He shook his head and filled it up little more. Andy seems to have been as close to what I did today. I pulled on the scale there and almost called the lady a lier when she said I was 13,300lbs. I was shocked. this was "dirty 3/4 minus" gravel. Peak of the pile at the top of the cab. Not filling the bed completely though. As Mel said we are suppose to handle a ton... 2000lbs. As the lady said, "your tires are squatting, you've got a good truck." My guague was the fact that I wasn't squatting real bad in the bed, We have that extra helper single spring on the top of the stack, and I was making contact, but didn't seem to be over stressed. Oh well. My baby did good, axle tube and rear breaks didn't seem hot at all when I laid hands on it, so I don't think there was any overheating at the axle ends. Oh yea andy I too was 30 mph on the way home tops. And I was also using my gauges as my guide... trans temp never above 180 and engine temp was also just a little above its normal mark... Yea I was kind of worried.
