"I have a 2000 Chevy C/K 3500 Used with a 5.7 liter Gas, Crew Cab total mileage is 92000. It took me a year to find this car used with such low mileage. They are hard to find because they are still in service and rock'n and rollin on the streets,freeway,and back roads of America.. Even though the Vehicle does not have the 454, the 350 does more than I asked.. I don't haul alot just a boat and trailer and it does just fine. "GAS MILEAGE" The big "CON" Lets be honest These trucks are not exactly designed for the best intreset of the conservationist. These trucks are designed to serve one purpose and one purpose only.."
"Bought in December, 1992 with 5 miles on it. Now has over 310,000 miles. Never been into the engine (7.4L). 2 alternators, 2 starters, new distributor, 1 fuel pump, and a carb rebuild. Plus 100 oil changes! Still runs great. Everything works. Ran 285,000 miles on the original spark plugs. Very comfortable to drive."
"This is the definition of a work truck. It will haul about anything you can fit in it. It will definatley haul more than it will stop. I filled the bed full of sand once and it hauled it just fine. The guy loading it said it weight around 5000 lbs. I don't know for sure, but it was close. It gets around 20mpg and about 18mpg pulling a heavy load. The only thing I can complain about is the PMD (pump mounted driver). It over heats way to easy and will burn itself out. When this happens, the truck will shut off like a light switch. I have driven this truck for about 100K and I have gone through 5 of these things at $65 each (used price, new about $250) I rewired the thing and let it hang over the radiatior hose so the fan will blow air on it and it hasen't failed me since. I have 320K on it and it still has all the power needed to haul what ever you want to. You CAN NOT over load it with fire wood. I tried a couple of times. You can stack it as high as you want, but it will not over load it. It will easily pull a 20,000 Lb trailer as long as you have trailor brakes. The power vs. fuel milage ratio is outstanding. The ride is a bit bumpy because the springs are so stiff. It rides alot better with about 2000 lbs in the bed. Overall, a fine heavy duty truck. You don't need to spend 30 grand or more to haul your camper or cabin cruiser boat. This will do it and get pretty good fuel milage to boot."
