    i'm looking at a 6500 series dump with a gas engine. it is the 8.1 with a 6.17 rear end.also has an allison automatic tranny. the price is right, and it is in excellant shape. anyone have any opinions about this type of set-up? i would prefer diesel but they seem very expensive or high milage comparitively. it will be used mostly as a tow vehicle for a 6-7 ton trailer. occasionally loads of dirt or rock. i don't see much need to tow with a load in the dump.
    thanks for the opinions,

    Depends on how you use it, will it be worked day in day out, say running all day without shutting off, be pushed to the limit often. If the truck will do the above you definitly need the diesel. However if it will be used for short trips and a few days aweek, I'd say go for the gasser. For instance if you just hauling a heavy load to the jobsite with a bobcat in tow, and then stay there all day the gasser would be perfect. Then if you do the above, and are running back and forth with loads all day, you need the diesel.

    To start off that truck is a 3 ton so its not a very heavy duty truck legally a F-550 would almost carry the same load. The second problem its got a 496 gas pot which I'am surprised it has the truck must be fairly new so it might be fuel injected it should get you 4-5 mpg max load it up 3mpg.

    The 3rd problem is that rotten automatic that thing sucks up 50% of the engines power it will make the truck burn twice as much fuel. You foot will be constantly to the floor you will be able to hear the gas tanks collaspsing inwards. If there as a fuel gauge in there you can watch the needle drop as you climb a hill :laugh:

    The reason why the truck is cheap is its a gas pot, 3 ton truck, Allison automatic its not what someone wants. A truck like that would make a good pit truck or a truck you only use on a site where it never goes on a public road if it does only goes once and a while.

    If you want to use the truck for your business and hope to save money with it not a chance. The truck will burn tons of fuel and when ever that Allison decided to blow up watch out very expensive to repair.

    the truck in question is one of the converted hertz/penske trucks. originally i thought it was a crazy combination. i did however, run into a driver on his way back to florida from tennessee with it and he had nothing but good things to say about it. he worked for a contractor in tampa and this was the third one of these trucks the contractor had bought over the last year. said the gas milage wasn't as good as a diesel but not that much worse either, maybe 2-3 mpg less than the same size trucks with a diesel. the driver drives them everyday and really liked it. very strong endorsement from him. thats what got me thinking if anyone else had experiance with them. thanks for the opinions, and keep them coming. i apprecate all the feedback i can get.

    Not even close, man. The F550's max. GVWR is 19,000, and the C6500 is available in a GVWR up to 26,000. The 8.1 gas is fuel injected, of course, as virtually every gas engine produced in the last 15 years is. With 6:17 gears it won't be great on gas but power will certainly not be a problem. If he gets a good deal on the truck it might make sense, with diesel being considerably more expensive than gas.

    milage is between 85,000 and 100,000. the comparable diesels i have been looking at are much higher milage. my thought was rebuilding an 8.1 wouldn't be as expensive as rebuilding a diesel. i could be wrong.
    thanks for the comments,

    Possibly not, but a rebuild on a diesel will get you another ~250,000-300,000 miles.
