Alright guys, I'm thinking of getting an new tandem dump truck. I have found a 2007 Peterbilt with a cat c-11 335hp engine and an 2008 KW with a cat C-13 350hp. The Peterbilt as been overhauled and as 340,000 miles and the KW only has 228,000 miles with no overhaul and it falls under the new emission laws. The 2007 does not have any emission laws. Both truck are the same price and in the same condition as far as beds tires and looks. Any advice would be great?

What tranny and is the final drive ratio? What type of suspensions? With only the info that you gave I would go with the Pete. I like the interiors better and of course no emission bs to deal with. I am not a fan of either of those engines.

Also what's the problem with engines?

The specs look good on both. The C-11 might be working harder and thus less MPG and life, perhaps why it had an early rebuild. I am surprised both have 24.5's. Looks like both were started as dump trucks and not road trucks converted to dump trucks.

The CAT engines are expensive to work on, and harder on fuel typically. Are both set up with a buck plate in the back with a pintal and air to the rear of the truck?

What is the money on these trucks? Can you post pictures?

No they do not have a pintal on the back. I will have to add that after I purchase. Yes they were both started as dump trucks and not road tractors converterd. I dont really want a road tractor converted. These trucks ar both listed @ $75500. I am leaning more to the Pete even tho it has more miles due to the emissions. I'll try to post pics later tomorrow after I get a few.

Unless everything is flat by you i'd try to find truck with bigger engines. None of these trucks will be speed demons. My Pete 335 single axle had a 300hp cat with a 8ll tranny. It had a 4.10 rear. It was only a 65 mph truck.

I'd also try to find a truck with atleast 46 rears.

That is about the last 2 years that Cat built engines for highway use. Cat had a lot of engine problems the last couple of years, which is why they got out of that business. Not sure how those engines are holding up longterm. You might try to find a "big truck forum", or Cat engine forum, with a discussion section about those specific Cat engines, and get some firsthand info.

So I Had a Deal come up today that I’m not sure I can pass up. Not what I’m in the market for, but think I my purchase just for a Stump and Boulder hauler. I have a Friend that has a 1990 GMC 8500 Tandem with 103,000 org. miles. 3126 Cat Engine 16' Bed not bent or dented at all just alittle wear in the bottom. All Aluminum Buds, New Rubber all the way around, Interior is in great condition and body is in great condition. Walking beam suspension Pintal Hitch and New Electric Tarp $9000. What to y’all think on this Truck?

I wouldn't buy any truck with under 400 horses that didn't have a 13 speed or better tranny. I'm a little biased toward high horsepower or a long legged tranny living in the PNW, we deal with quite a bit of elevation gain. I drive a truck with 400 horses and a 10 speed, most days it's not even close to enough dragging a trailer.

That should be the perfect truck for what you want to do. I have a slightly smaller version of that truck, a 92 Kodiak. Mine has the smaller, 3116 Cat engine and a 10 spd trans. I can run up and down hills, towing a heavily loaded tandem dual gooseneck full of firewood, at 65-70 mph, with no problems. My truck, trailer, and load, are grossing about 35,000. I never have to shift out of 10th, even on long uphill grades.
The price sounds good too. I would really say that might be the deal for you now. You can always upgrade to a larger truck later if you need to.

That's an aweful deal run away, can I have his number so I can call and tell him what an aweful deal it is and buy it from him so no one has to get that aweful deal!
Joking aside, not a bad price but the motor is a downside. It has the same motor that is in my F650 and I can't imagine being a tandem with that motor. I get different transmission but I bet with that truck your always going to want more hp.

If it is a '90 then it would be a 3116 not the 3126. What is the transmission? If it's in decent shape it sounds good.

I would really hesitate on a GMC truck of that vintage. My dad just sold his '89 5 yard, which ran well but he found it nearly impossible to get parts for it. GM is not providing parts support for many of the parts that are unique to heavy trucks. For example, he needed a throttle cable and ended up having to get one custom made.
