Opinions wanted: 2007 Duramax 2500HD (Vehicle has been purchased)

Would like some opinions on a GMC I am looking at. It's a 2007 GMC Sierria 2500HD Diesel. Has 97k (just under) on it. Local truck. Bought and traded back into the same dealership which happens to be the dealership in my town that I use. My closest friend happens to be their Diesel Tech. Although it's 9-10 years old NADA and KBB have this truck valued at what the dealer is asking for it. I expect to pay a bit less of course. It puts the truck in the I can afford range. Just not sure about the age even though the mileage is low.


Opinions on this truck? I know it will more than handle my towing needs. I like the idea of having the towing power and the fact that they get decent mpg when not towing.

Truck sure looks nice and appears to be well kept. Check certified labels to make sure your getting the weight capacity your looking for before purchasing. When I purchase my 2500 Duramax I was expecting 2793lbs payload as advertised but when I actually looked at the label the payload stamped on my truck is 2214lbs. This loss of 579lbs really crimped and decreased my 5er trailer options.

Not sure if your pulling a 5er or a TT but the payload is very important to the proper 5er selection.

Thanks for the quick reply! From another Minnesotan at that!

My 1550 has a payload of 1585 so even if this one is only 2214 that gives me an additional 600+, so I would be good there.

Not pulling a 5er. MAX on my toyhauler is 9700. I'll be in the 6500-7200 range when loaded with both of our motorcycles and all of our gear etc.

Should be a good truck and more than capable for what you want. Check to see if it's the LBZ or the LMM Duramax. They switched mid year to the LMM which has the DPF (diesel particulate filter). Many do a DPF delete on the LMMs.

Opinions wanted: 2007 Duramax 2500HD

It's the classic model that Chevy/GMC made for 2007. It should have the LBZ engine. They produced extra 2006 engines and put them in early classic body styles as a way around the new emission stuff. I have a 2007 Chevy with the LBZ I bought brand new in Feb of 2007. It's been trouble free for 97,000 miles.

Looks like a nice clean truck and should have many more miles left in her. Click image for larger version

I have a 2007 gmc 2500. It's rated to tow 14,500 lbs and i tow a 2008 flagstaff which weighs 7800 lbs. So weight wise you would be well within the tow range. Just make sure the glow plugs have been replaced and anti seize placed on the new ones. If they haven't and one breaks while being replaced the heads have to be pulled in order to get the broken part removed. I had two go bad with only 60,000 miles and didn't get them replaced until 80,000 miles. I was lucky because none broke. Had one broken I would have been out about $1,500.00 per head. This is very important. Other than that I love my truck. Coming back from Arizona a couple of years ago I averaged 16.6 mpg pulling my fifth wheel. Of course I had a tail wind. I get 21mpg right along pulling nothing.

I had a 2002 Chevy diesel Duramax crew cab 2500HD that we loved! It pulled my 2003 5th wheel Everest that had 3 slides and was 36 foot long. It weighed over 12K. W/O trailer, I got 18 to 19mpg. With 5th wheel, I got 11.or 12 mpg. Only on one long, big Hill would it loose power going up the hill in MI. Otherwise, I could cruise at 70 mpg all day without any issues. Got it with 33K miles (had injectors replaced shortly after purchase under warranty), bought a new Cedar Creek 38FL with 5 slides and sold the truck with 160K miles. Loved it then, miss it now! Replaced it with a F-450 Lariat diesel 4WD and dually which pulls the CC like it wasn'the there. Good bye to gas mileage, now am lucky when I get 10 mpg.
Good luck with the GMC diesel duramax, I know you will enjoy it!

I have a 2007 GMC Sierra 3500 with the LBZ engine and 125K miles on it. I bought it used in 2009. In the 85K miles that I have owned it I have done regular maintenance and replaced the oxygen sensor, transmission lines and brake lines and had a couple of parts in the steering replaced. I am happy with this truck and I cannot imagine trading it for anything else.

I have a 2007 Silverado 2500HD - it's an "early" 2007 so is the "Classic" with the LBZ engine and no DPF. Pulled my 6500 pound Rockwood TT like it wasn't even there. The only issue I've had with the truck is front wheel ABS sensors... a known problem where corrosion builds up on the sensor causing it to back out of the wheel hub and lose signal. I replaced both of those myself for about $50 apiece. Other than that it's been a great truck. Wouldn't trade it for a newer diesel with the DPF and DEF requirement.

If its a good one with no rust buy it !!! it pulls my 5th all day at 63-65 mph at 1600 rpm and gets 11 to 12 MPG consistent. Replaced rear wheel seal , one glow plug and a brake line so far. not bad for 93000. Its NOT For Sale im keeping this one

I looked-up the OP's 2007 GMC on AutoTrader and it appears they want $27,381 for a nearly 10 year-old 3/4 diesel with minimal interior upgrades (and exposed to MN road salt)... Yikes! It would have to be a Southern truck with NO RUST for me to offer $20K... Also, IMO diesels should be paired with 1 ton frames so that you still have plenty of payload. Since used diesels cost so much more than same-year gassers, it's nice to know that if you DO upgrade to a 5er, you don't have to find yet ANOTHER truck with more payload...

In comparison, in 2013 we bought a 2 year-old (2011) Ram 2500 CC w/5.7 Hemi, NO RUST, and the balance of the 5 year/100K mile powertrain warranty for $14K... (I drove it for another 1.5 years before the warranty expired & good thing - had warranty work done in that period...) It has a payload of 3,000 compared to diesel 3/4 tons that are typically below 2,500... We had no trouble towing our 8,000 lb. (loaded) TT w/TV payload of 2,500+ throughout the Smoky Mountains. Newer (gas) technology means I get 15-17 mpg on my daily commute and 8-10 towing. (In comparison, gas engine & tranny tech from 2004-2007 provided lower mpg...)

I DO agree that diesels are better at towing than gassers, but NOT worth paying $10K more for something 4-5 years older... IMO the OP should find a newer truck if he is shopping in the $25K range, not something 10 years old that has (likely) been exposed to many years of MN road salt...

Based on your relationship with the dealer I would say buy it. You should be able to get several more years out of it before it begins to rust.

I absolutely LOVE my 2008 Duramax; just wish I got 4 wheel drive when I bought it.

Only trouble I had was a leaking transmission hose that was repaired under a recall and I had a fuel injector replaced at the 7 year point.

Still runs like a top!

I have a 2007 GMC Sierra Classic with the Duramax LBZ. It has been a great truck.

Pros: no DPF, no DEF, the bugs from earlier versions of Duramax are all worked out, 6 speed auto trans (2005 and earlier have a 5 speed). Very solid engine and transmission.

Cons: The electronics (multimedia center, DIC, etc) are not as nifty as a new truck.

I was shopping for a new truck recently. I didn't hear any difference in loudness.

Sadly, I am selling mine because I need a dually for a FW I am buying. I really wish I could keep it.

The engine and transmission should be OK with 97000 miles, but other parts of the truck may need repairs soon. The usual things that wear out like starter, water pump etc.

The LBZ is very desirable and get a higher price.

... said the guy who is trying to sell his 2007 GMC for a new 2016 Ram 3500 because he needs more payload...

If the OP is financing this approx. $25K purchase, then it is a really bad deal... In December I could have gotten a NEW (remaining stock) 2015 Ram 3500 CC 4WD w/Cummins TD for $38K whereas the OP wants to buy a 10 year-old GMC 3/4 ton which is currently listed on AutoTrader for $27K... (not sure what he will talk dealer down to - but most don't inflate AutoTrader price so that they can attract more sales...)

That's only a difference of $1000 per year of ownership, so I'd rather extend my payments another 2 years and get the new truck that will last 10 years longer... Financing an older truck typically means bringing money to the table, a higher interest rate, and higher payments due to the shorter allowable term.

IMO, a 2-3 year-old truck is a better bang-for-buck... For my (used) 2011 Ram 2500 CC purchased in 2013 I paid $0 down and with 3.5% interest my payments are only $200/month... I pay $500/month, same as had I bought new, so it will be paid-off soon... Current trade-in value is the same as what I paid since I added a like-new fiberglass cap found on CL for $500...

I'm NOT saying the GMC is a bad truck, it's just a bad deal unless he can get it for a lot less...
