My rear window is a R H Laurence ( I think that's the name)Manual Sliding Deep Tint. The dealer had it installed for me before I even saw the truck.The day after I took delivery it rained hard, and I noticed some water inside the track the glass slides in. I was just about to start screaming when I noticed that the installers had not latched the window completely. I couldn't see any more coming in after that. It's going to rain again tommorrow so I check it out. It's been too cold to spray it with a hose until today.
I am glad that I got the 8100/Allison/4.10 it really has alot of power and the mileage so far doesn't seem any worse than my Dodge 250. I'll do an accurate test after I get 1000 miles or so.
Good luck with your truck I know your going to love it.

it's a truck tranny for heavens sake!
Good news I've finally got a build date Feb.19th and shipped on the 23rd. I ordered it on Dec.1st.
That would be the 2500 ext.cab. Sierra w/8.1 allison and 3.73 trans.
I have a Vehicle Order number is there any way to track it with that number, I noticed a few others asking the same question ?????
Im still waiting..8.1 ally, 4/4, 4 door 373 LS.BLk,
hope this helps .....Geo
clunk when going in and out of park is supposed to be normal as well
I don't know if anyone has ordered the trailer type mirrors instead of the regular electric mirrors. I had ordered them but switched them back to the original ones after a friend got his and didn't like them for towing. He missed being able to see his trailer wheels when turning a corner. You could either adjust them for looking at the wheels or for looking at the other lane but not both. With slide on extension mirrors you can have one set up for the lane and the other for the wheels. It's not a bad set up once you get used to it.
Would be interested in other opinions of others who tow.
but I would go 4:10's...as it is what I have planned with an 8.1 CC Ali...
trailer towing package on 11/13/00.The dealer informed me a week later that the order was accepted and a built date was from the middle to late February. And delivery date to dealer would be the middle of March of this year. People have stated that they are getting, on the average, about 12 mpg. That's not bad. My 86 Sub. w/454, Doug Thorley headers and free flowing mufflers, get 7.3 mpg. Hauls asp. Neighbors love the rumble, when I start it up. Just a kid at heart.
perhaps they will have 2-tone...auto-trac or a power slider or moonroof by then?
Test drove a 8.1 w/Allison, 4.1 rear end. Thought my 86 Sub. 454 w/Thorley headers was faster. Allison trans was very smooth and shifted quickly, just like a close ratio gear box in a Vet. Wonder how it will perform with our 30' travel trailer connected.
The HD's I see on the lots only have cloth seats. Two months ago they all had leather seats.
It seems that the higher the volume of trucks the dealer sells the less trouble they have getting the special ordered ones. Next time I order one I'm going to check out the "big boys uptown" 1st. Also check out gmbuypower.com. You can click in any zip code and scan the inventory of all the dealers in that area. The waiting time not only depends on the dealers "pecking order" but also availability of options etc. wheels.com has good info. on factory holds etc. Last but not least take it with a grain of salt,if the dealer tells you 8 to 10 weeks. Most take 3-4 mo. Lots of luck.
I also added a set of BFG All Terrain T/A's in 265/75. The new treads are approximately 1" taller than the 245's but I can't detect any difference in power. My tire dealer suggests the speedometer will be off by 2 miles per hour. Appearance alone is worth the investment. Also added a color matched hard tonneau cover and tinted windows.
Why the bigger tires ? Is it to just fill the wheel well ?
Wonder how a 8.1 would perform with headers ?
2. Longer lasting than factory.
3. Better Wet and Snow traction
4. Better off road traction
5. Look Better
6. Look like they were made for the vehicle
7. A slightly higher overall OD ratio for improved milage with big motors.
8. GROUND CLEARANCE!
Or...... taking them off and going without. Is that a viable option or will the button holes look even worse?
Got the snow plow prep package, but can't get an answer on what the beefier front suspension is rated at. Anyone know? Also, where are GMC's built? Hope to have mine in May.
My LT 8100/alli is in shipment and will probably be in around 26th to 28th.
I have requested dealer to remove the 'Ugly Black Flairs' as soon as it gets in for the same reason you all have stated.
Question on what the fender is shaped like when the flairs are REMOVED?????
I have been looking at units without Flairs and I have ASSUMED that the fenders are standard shape for example like the 1500's.
They have a nice 'formed into the metal die' flaired shape which doesn't look tacky and added on.
Can you tell me if this is correct or what if not??
Also where is the 'doulbe faced tape' atachment at exactly??
I'm planning to just re-install the Black attachment Buttons back in the holes they came out of when the FLAIRS are removed. Will that work??
I know there will me no molding now around the wheel well but neither do the 1500's as far as i can tell. Also on my older F150 that had chrome molding it was just a place for COROSSION to set in.
Help anyone with advise on this because I probably wont see this thing while the flairs are being removed to change my mind.
Thanks in advance-- 75v
With regard to tires, my 265's fit without any changes to the rims, shifting, or clearance. If anyone wants to see what the flares, 265 tires, hard tonneau cover, tinted windows or Bed Rug look like, give me an address and I'll forward pictures.
How is everyone making out? Are the aftermarket parts there yet for this bodystyle? I am looking for (when truck arrives) a bug guard, window vents, nerf bars...etc. Have all these parts surfaced yet? What about hypertech? Thanks for any replies.
Have I made the correct assumption that they are??
I just want to get back to the metal formed fender shape like the 1500's.
Just was hoping some one had already 'Been Their/Done That' and would be able to say for certain.
I'll find out in due time i guess!!
I will report back on the mileage after I have driven a while.
My GMC 8.1 2500HD 4wd will be shipped in April, all the way to So. Korea, and I plan to be firm on any damages. Have seen some vehicles arrive "totaled", as they drop the containers 50-100 feet sometimes!
Ordered Sept. 5 came in February 26th.
Many thanks to all of you for the great information over the last three years.
I have been following this forum since the '99s cameout with GM's stupid 3-door Marketing decission. Refused to buy the 3-dr especially when Ford and Dodge already had 4-drs on the road.
This forum has helped really pass the time cause I could at least appreciate when others received their units and share with those of us waiting on units or trying to decide which to order.
From the Humor by some, the PUT DOWNS by others and the overall just good information.
Thanks - So I'm hooked and will keep following and help with info when its desired.
Poco -- Thanks to you and those before you for keeping things going in a polite, friendly and 'PG' rated atmosphere.

On another note, my '99 Classic 350, Z-71 Extended w/ 3.42 only got 11.5 mpg constantly, so I guess I will be extremely happy with my 8.1/3.73 combo...
