2008 gmc dually info

Can't speak to price other than the lbz trucks do hold high resale due to last of the no dpf/def trucks for those who want to not have that and be legal. Also have 6 speed Allison. Watch for leaking transfer case (search pump rub) and also the tranny line leaks.

2007 duramax classic 4X4 80kmiles for 24k, should I consider this one ?what do I look for?

I've had mine since new with 104K miles. Only limped home once and that was from the dealer who had just serviced it. You can't sync blue tooth to the audio unit.

This truck truck does not use DEF but runs a regen cycle every 500 to 800 miles depending on your driving. I'm averaging 16 mpg bobtailed and 8.5 to 9 towing my 42' fifth wheel. You'll notice a drop in fuel economy when the regen cycle is running. I have a Scan Gauge II on my truck and can tell when the regen is in progress. You don't want to shut the truck off when its running the regen. The turbo pressure will be low when it running the regen and egt temps high. Run the truck hard and it will take care of you.

It's an awesome truck, reliable and powerful. I'd snatch it up because they are hard to find in my area, at least.

The low towing MPG speaks to the issues of the early DPF trucks.
While they are OK trucks. The 1st generation DPF trucks suffered from poor MPG's. I would prefer a later model year 2011 or newer. DEF was introduced by then. The frames/suspensions were also beefed up and payload ratings where increased.
The manufacturers learned from their mistakes. Diesels of the era were OK. However the next generation was a drastic improvement. Emission technology improved and so did MPG's
I consider the 2008 era the learning curve period when it comes to diesel emissions.I would avoid diesels of this era simply because better emissions technology has produced better more efficient trucks since then.

Complexity isn't always better. The first def trucks had many teething problems. Still are with a 9th injector recall.

In your reading search cp4 versus cp3. Actually the duramax lmm engine is very reliable (2007.5 - 2010) and had few if any dpf issues. Far more pain with the ram and fords in that first year. I'd still have a knowledgeable diesel mech look over any used truck - pull codes - check for leaks etc. Tranny line leaks are one of the only common issues in that year.

Can you say cp3 and reliable at the same time?

The point is the reliable lmm has the cp3.

Unfortunately the guy flaked, he thought I was a scammer. I had cash ready. Oh well maybe I called his bluff. I'm still looking. So what Chevy or gMc should I get ? I have 40k to spend

I think that's one of the first years for the DPF...if not the first...

IMHO... I would steer away from any of the big three first year DPF trucks.

I recommend going for a truck a little newer and getting the DEF and DPF... the MPG is better and the manufacturers figured out the new emissions better.

Just google 2008 Duramax DPF and read all the users wanting to get rid of the DPF on these trucks.

Another option is to go with a little older truck...2006 or 2007...considered to be one of the most desirable Duramax years.

Thanks, and again....JMHO.

I agree 100%. Those first couple of years with new emissions was a real learning curve for all of them. Actually it took Ram a couple of years longer than the other two.

I think it's a little high. Got my 2005 Ford CC diesel 4X4 with 11,000 miles on it for $25K from a dealer. Have you called around to the dealers to see what they have as comparisons?

Unfortunately...a bad comparison...the 2004 thru 2007 6.0 diesel Fords have the lowest resale value of any of the Big Three diesels...some might think you actually paid too much...

ROTFLMAO :B

I have the same truck with 41,000 miles on it. I do have 4 wheel drive, but I would not sell it for anything less than the 32K he's asking even w/o 4WD. Price it against a new one and the 32K looks reasonable. Good luck whatever you decide.
