GMC Sierra/Chevy Silverado 2500 & 3500 - II



  • Seeing as we are switching to a new section for the New Sierra/Silverado 2500 & 3500 Topic I would like to take this opportunity ask all new purchasers of the 8.1 for their input.
    I would like to find out what your towing experience is and mpg or anything else that you think would be of interest to a potential buyer.
    Any problems with the SES light ??
    All information would be appreciated, thanks.

    My business just bought one that my partner will drive.He picked it up on Tuesday. I drove from his house to the service station for new tires. It only had 20 miles on it and I was driving through a housing development. It feels real good! I drive a 00 2500 and the HD is a lot different. I'm sure the 4:10 rear end has a little to do with that. It feels like a lot of power. If you like power I don't think the little bit of difference in gas mileage will make much difference.

    I can't wait to drive it when it's got some miles on it. That is if let me [turn it loose].

    I ordered mine from Huffines for $500.00 over. I placed the order with the dealer on Aug 02. It seems the 8.1 was on constraint for a long time. I now have a build date of Dec 04. GM tells me it may be here before Christmas. The Power Tour was in my area about two weeks ago and one of the guys that does the driving said the 8.1 was getting between 9 and 10 towing one of the large trailers. He also said the DMAX was getting 15 towing the same type of trailer. The Power Tour is geared for selling the DMAX. I cannot see paying that much extra for the diesel and the only reason I ordered the 8.1 is so I could get the Allison trans.

    You asked if anyone knows for sure if the Duramax has Aluminum heads. Yes they do I took delivery of my truck on Nov. 1st.

  • In response to #563, my surburban has a bad "reverberation" when running at highway speeds with the back windows down. In fact, it's so bad it will run you out of the truck. So, needless to say, we keep the back windows up when on the highway. The kids don't appreciate that, but my ears can't take the pounding. I'm one of the 2 guys in here who prefer the manual transmission and after reading about the guy who wore out 3 automatics towing with ford's and gm's, I plan on staying with that attitude. I'm sure the allison is a better transmission, but at 2,000 bucks, it better be. I just don't won't to be the one to pay all that money to find out.

  • Hey richard, I see you are in here. Any mileage reports for us with that duramax of yours?

  • 4x44x4 Posts: 114
    I would really like to see someone's 8.1L MPG's...everyone keeps saying the mileage will not be too much different than the 6.0..I just don't see it..365CU VS 496CU..I have gotten 14 on highway and 12 city..4Wheeler Mag tested the DMAX and 8.1L and there mileage reports for mixed driving was 15.8-DMAX and 9.1MPG for 8.1..unloaded ext cab 4x4's..

    I could see maybe the 8.1 getting better MPG's if the 6.0 needed to work harder to push the truck but i don't see that at all..Honestly, I feel the 6.0 has a lot of power and hauls butt...again if i towed a lot i would get the 8.1/allison combo but the most i tow is a 22 ft bay boat...

    anyway , I would like to see some REAL LIFE numbers from someone with 8.1 and 4.10...
  • I ordered a 2500 HD with a HD NVG manual tranny.
    Did I make a mistake? I wont be towing an
    incredible amount at least not for now. Has
    anybody ever driven the manual, how does it feel?
    I would appreciate some input while there is still
    time to change my order if I want to. Mileage i
    figure would be around the same since fourth in the
    auto and 5th in the manual are the same and I do
    alot of freeway driving....please help me out with
    this decision...

    be posting GPM's for the 8.1 but there just aren't many of us who have taken delivery yet due to the Constraint eairlier.

    Better note that the MOST of the early 8.1's ordered by Dealers for inventory have the 4.10 gear ratio -- all gm would allow for the non-sold dealer units - think they wanted to show off the power better as if it needed it.


    mth1 -- Glad to see your TPW post. Means maybe my Sept. 05 tpw should show up in about 30 days.
    (13 weeks and counting)

    I would also like to see the mpg numbers for the 8.1. I am doing my research on buying another Crew Cab, but will probably go with the 6.0 because of mileage.

    I owned a 99 CC 4wd SB with the 7.4 liter and 3.73 gears and only got 9 MPG in the city and never even got 12 MPG on the highway. I would have hated to see what it would have gotten towing anything heavy. I sure would like to see some numbers.
  • mgdvhmanmgdvhman Posts: 4,162 need to WAIT! can we give results as a whole when they are barely out? Someones mileage with 4 tanks of gas isn't hardly a good idea of longer term....

    By 2002 Model years coming out we will have a better Idea what's up.......

  • I had an opportunity to test drive an XC, LB, 2500 HD with an 8.1 and 4.10 gears this weekend. The power and acceleration were very impressive. If MPG are within reasonable limits, I'll buy this combination. Woolyback, I ordered white as well. Hate to complain about a truck I can't even get, but what's the deal with the black flares. My dealer advises they can't be deleted nor removed, only repainted to match. Curious why GMC would do this.
  • I just bought 2001 2500hd lb from Denoyer in Albany. A real good bunch of salemen. They had several 2500hd on their lot. Please send me an e-mail if I can assist anymore

    Be Removed. Standard painted metal underneath like what you see on the 1500's.

    Dealer removing mine first thing off the carrier!!

    this flair question comes up. I enjoy the heck out of your pictures and your comments. And your the only one that post splash guards that fit the flairs and I thank you for that if i should leave them on.

    But I won't -

    Have this BAD thing about engineers not designing things into the truck in the first place and then to make up for that 'mistake' throwing a piece of plastic on as to what looks to me as an afterthought. Then to top it off GM tries to save money by not even painting 'em to match UNLESS YOU GET PUTER!!

    But your truck does look very good the way your guards fit the flairs. I'm glad to know that so Thanks and please don't be toooooo upset with us'ens that don't like the d**! things. :-)

    Keep those picture coming - your right that this would be a lot of ZZZZZZZZZZZZ's but for you.

    Wait 'till a bash someday....

    Richard, how fast are your highway miles, I am Really Curious of the Milage going 75-80mph and what RPMS you are turning as this is what I normally drive. Do you have 245 or 265, and what is your setup (4x4),I forgot(Too much Turkey and hunting). I would be really happy to average 18 with the duramax if I order one, my half ton only gets 14 going 75-80 so it would be an improvement, even with Diesel $.20 higher than Gas in Illinois. I hope all of you had a great thanksgiving. I am with Ryan and Like the flares, although on the Polo Green GMC that I would order, they are Painted, Oh well.

    Best Wishes,

    Im not mad your taking them off. I have become to be known as the flare guy. Im not gonna hold it against you or anything the trucks look great with them and without them.

  • OK, I am back "on-the-air,' full of turkey and ???. I don't know the GM numbers on the manuals, but when I get them I will post them. I will keep this post as a reminder. I get all the manuals and use them all at one time or another. I have a F250, 1988 4x4 and have used every manual in the bunch - the latest was this weekend when the clutch went out. Fortunately it was only the clutch master cylinder instead of the slave cylinder - you have to pull the transmission to replace this one and I have already enjoyed that once. You ought to try this in light rain at 32 degrees - it builds character! So the manuals come in handy if you are a do-it-yourselfer. I may not sell the F250 when I get the 2500HD, as I may not be able to sell myself on the idea of driving thru the barnyard in 6 inches of cow/bull do-do with the new one - but then again I might. Why am I buying it - certainly no logical reason, it is just that I WANT IT.
    My color is BLACK with Graphite interior - LT with leather seats - another real nice convenience when you have wrenches and fence pliers in your pocket and grease on your butt. Think I should keep the Ford? I like your color of Indigo blue. Was going to get red, but I already own 2 red cars.
    No, Ryan didn't straighten me out on the Z71 question before the ink was dry, but loyalgmcguy did. Thanks loyal one.
  • mgdvhmanmgdvhman Posts: 4,162
    you want an LT for riding thru Cow do do??

    I hunt on a dairy farm and see the insides of the farmers thanks

    While I'm thinking of it I was under my truck the other day and I noticed the frame is marked 35743 not 25743 as it should be on a 2500HD crew cab. This should denote a 1ton if I am correct. Can anyone tell me the difference if any in these frames,brakes,suspension etc? Did I get a 1ton with 2500HD badges? The truck was built the first wk. of Oct. Anybody got any thoughts on this?
  • I kind of like the ugly black flares myself on the white truck but according to the brochure the SLE/SLT models will eventually only come with white flares.
    There is a little footnote regarding the black flares that says the "Color will be Summit White interim 2001 model year".
    So when I eventually get mine they may only be shipping with white flares on the white trucks.

    Regarding the 8.1 with 4.1 or 3.73 ratio is anyone out there towing with either combination.

    mgdvhman --- you're probably right about waiting for awhile to get more input on the mpg for the 8.1 but I'm afraid I don't have your patience to wait until the 2002 models come out. The mileage doesn't change that drastically on a new truck at least it never has on any of mine. However that can be factored in when it comes time to evaluate the responses new buyers may submit.
  • So nobody has a comment on the manual that comes in the 2500 HD with the 6.0L (NVG 4500)?
  • I think when they went to the new HD class the 2500's are actually ton chassis and the 3500's are duallys only. In the past you could order a single rear wheel one ton or dual rear wheel all 3500's. In this new class the LD 2500 is 8600 gvw the HD is 9200 gvw. all the old style 3500's were 9200gvw in the single wheel set-up.
    Hope this helps,

    When I ordered up my new Dodge a couple years ago the dealer was preping a special order truck for a livestock farmer. All leater interior but vynyl flooring instead of carpet. This was all decked out sans carpet. The salesman said the guy wanted a nice truck that he could work and would be easy to clean.
