#1 of 109 Anybody have this truck? Any problem issues?
Jul 03, 2002 (10:55 am)
This is one of the two trucks I'm thinking about getting. It will either be the 2500HD Duramax diesel w/ the Allison transmission or the Ford F250 Super Duty. I trust the Ford more but like the looks (both interior & exterior) of the GMC product. I will get the 4x4, Crew Cab model.
I had a 1986 Chevy S-10 Blazer and it was a slug and maintenance was out of line. I haven't had a GM product since. I have a F150 Supercrew now but need more power for pulling our boat. I recently got a whopping 7.5 MPG on a trip from San Diego to Lake Powell.

7.5 mpg pulling a boat? That is WONDERFUL! My 1988 F250 gets 7.3 pulling nothing but a few odds and ends in the back. I have gotten as high as 8 mpg-and this pickup is a real slug. You need to plan ahead when you are about to pass someone. On the other hand, my 2001 2500HD with 8.1/allison gets 10 around town and 13.5 on the road and it has loads of power. I am very happy with it. cowboyjohn

I have a 2002 GMC 2500HD and so far it's great. Mine is a 2WD Crew Cab with Duramax and 6 speed manual. I get 21 MPG commuting and 15 MPG pulling a 25ft 5th wheel. It has all the power I can use (even climbing I-70 west of Denver with the camper on tow...65 MPH and power to spare).
I'd recommend you research the two trucks you mention at www.ford-diesel.com (for the ford) and www.thedieselpage.com (for the gm). I did, and both sites contain loads of good information in the forums.

Our fleet of Duramax 6.6's with the Allison transmission have been the best investment our firm has made in vehicles in years! So far, great performance, great dependability and the crews tell me they like the way they handle, climb hills, descend hills and the fuel economy. The only modifications we have made are:1.when due for replacement we have increased the tire size from LT245-75-R16 E to LT 265-75-R16 E. 2. Replaced the stock exhaust systems with a stainlees steel five inch (OD) exhaust system. We are planning to replace the other half of the fleet in our new fiscal year and we have already decided NOT to go to bid. We will negotiate with our local Chevy dealers and take the best deal offered.

The last two Powerstrokes I bought were each brand new, a 1997 F250 Crew Cab short bed 4x4 (last year of the old body style)and a 1999 F250 Crew Cab short bed 4x4. The 97 developed a chronic water pump leak with less than 10K on the odometer. The 99 began leaking oil at the rear main seal just under 3k. The heavy duty truck division of my dealers service department said the engine would have to be pulled to replace the rear main seal. Though I hated to live with the leak, I decided it was better than having the engine pulled. Right or wrong it was my decision to make. I now own an F150 SuperCrew 4x4 but must admit that I am both intrigued and drawn to the lifted skirt and perfumed inner thigh of the Duramax diesel and Allison transmission. I have followed this engine since it was first announced that Isuzu would be developing the engine for GM. Several of my customers own this combination and all seem to be very happy with their trucks. I miss driving a diesel and think I'm going to give the GMC a try on my next purchase. GM needs to put this same combination in the new Hummer H2.

I would like a little bit of info on your truck. I'm thinking about purchasing the Duramax w/the 6 speed manual. None of the local dealers stock the manual and I was wondering how it drives. Is the clutch overly stiff or easy to push down? Is your 21MPG in the city or on the highway? Thanks for the info.

I purchased my 2500HD,2002 in Jan.. At 1500 miles I was getting 20 mpg, at 75 mph, once it breaks in they say I will get more. I talked to one guy who advised me he was getting 24 mpg.
This is the best truck I have ever owned! The factory tires and rims were a bit too small so I purchased 8 inch rims and LT285-75-R16. The ride and look is much better!

I am a Air Condition serviceman in Houston and I have talked to a few guys running service out of the DURAMAX.
The main issue with these trucks is the Allison 5 speed auto.
It's not that they break, it's that for some strange reason they will downshift for no reason at cruising speed, redlining the motor, and scaring the HELL out of the driver. I have heard this from several people.
And of course the dealer can NEVER duplicate the problem so you have got to live with it.
By the way, every guy i talked to is getting about 15 to 16 MPG overall. Same as a Powerstroke.

My husband has wanted this truck since he read about it in popular science. I didn't want to spend the $ but since we purchased it - We both love it. My husband tends to have a lead foot so I thought this diesel would slow him down - how wrong I am. He can easily burn rubber with an empty bed.
This truck is used for flooring installation business so it is always carrying or towing lots of weight. It is one great work horse.
We got the leather, power heated seats & they are worth every extra dollar we paid. This truck rides & drives so nice, I enjoy it more than my own vehicle. The engine is very quiet compared to the Ford diesel motor.
This truck is rated a 10 in my book.
