I kinda wish I had traded my 2000 GMC Sierra 1500 Ext 4x4 SLT, for a 2000 GMC Sierra 2500 CC SB 4x4, 6.5L, SLT, loaded. The sad part is that this truck invoices less than 32000, and they had a few thousand incentives on them. Could have been had for less than $30,000. I know the diesel isn't a duramax, but I have drove one, and they are a very nice engine with a 100k warranty on it. A new 2001 like my 1500 Ext cab, invoices over $29,000. And go price a new CC 4x4 SLT D/A. Gonna be over $37,000 loaded up INVOICE. And Im sure the prices will be even higher on all the GM trucks. GM is just about pricing everone out of being able to afford a truck. I know the D/A 2500HD is a heck of a truck, but is it worth $8000 plus more next year to buy than that 2000 was. Hunter

Are you running 285x75x16 tires on your truck? If so, what brand and how do you like them on the truck. Did they fit on your truck without a lift? The 285's are supposed to be 33 inches tall compared to the stock 245's which are closer to 30.5 inches tall not to mention probably at least an inch or two wider. Also, are you running 7" or 8" rims? Any info would be appreciated. My 2500HD 4x4 EC is supposed to show up at the dealer sometime this next week and the first thing I want to do (besides a spray-on bed liner) is get rid of those little 245's. Have you experienced any noticeable drop in power with the bigger tires? I was considering having the computer reprogrammed, but was going to wait and see what the truck ran like with the bigger tires. Based on my calculations, the 285's should have about the same effect as running the 245's with the 3.73 gear. Mileage should also be off by close to 10% which could explain your 11 mpg.

#714 of 1057 DUH! by ryanbab Apr 14, 2001 (9:24 pm)
Tim i was just saying i liked the BFG's. He asked what kinda tires people are running. Just thought id give my opinion Also the BFG AT's do create a little more road noise than my 265 fstones (garbage)

Which 2500HD Do I want?? Want to buy a 2001 Silverado Extended Cab 2500HD, 2WD, Shortbed. Plan to use it with a Lance camper shortbed 2,200lb and pull a boat weighing up to 5,000lbs. One-half the time I'll drive it without either. Was planning on getting the 6.0liter V-8 but now leaning toward the 8.1liter V-8 with the Allison. Would like the gas mileage and price of the 6.0 liter but wonder if that's a mistake in the long run. Also, what is the gas mileage difference between the two. Appreciate any suggestions...

whatsa- i went with the dunlops on the factory wheels.as far as a drop in power i dont know because i changed them after the first day and i think it made the truck look tons better.i wasnt sure how far off the milelage would be but the guy at shop said dont even worry about reprogramming the speedometer because it was very little difference.truck runs great though...
#718 of 1057 Brake Controllers by trucks4me2 Apr 19, 2001 (8:32 pm)
Thanks for the inputs on the Brake Controllers. I will study the Tekonsha's. I also just heard that Tekonsha is coming out in May with a new one called the Prodigy which will be all digital. It will also mount in any angle and needs no level adjustment. Sounds interesting. Thanks again.
