The Avlanche2500 is built on a rugged frame with rear leaf springs and torsion bars up front. The 8.1 liter engine is standard with a HD four-speed transmission. This beast is heavy-duty, powerful, versatile, durable yet has a comfortable ride. Just ask the people who own one...
My first Avalanche2500 was a 2003. After learning Chevrolet was discontinuing the three-quarter-ton version, I replaced my first with this 2006 Avalanche2500. Now after twenty years and 200,000 miles I thought it may be time to replace it.
WRONG! After searching, I came to the conclusion that there's not any truck made today that would match this Avalanche. So its' definitely going to be a keeper.
What the Avalanche2500 does best, pulling trailers. Accounting for half the mileage.

Dang, that's a nice truck, OCG.
What kind of mileage do you get, pulling trailers or just driving without a load?
You can't expect great fuel economy from an 8.1-liter engine built for heavy towing. I didn't purchase the Avalanche 2500 for that. During highway driving without a trailer, you can anticipate a maximum of 14 MPG. However, towing a 12,000-pound load reduces fuel efficiency to roughly 7 MPG.
Being 20 years old with a quarter million miles on the clock, I was thinking to purchase a replacement. After seeing what's out there today, along with the cost. There's no way... Even if I have to rebuild both the engine and transmission I'm better off keeping her..
That's a good endorsement. Especially for a towing vehicle.
Over the past 20 years most of the miles have been towing a trailer.
Last year I got excited when I saw what appeared as an Avalanche at the local Chevy dealer. First thing I noted was the 8 bolt hubs. Meaning it was a 3/4 ton. My enthusiasm quickly diminished when it was an EV. And told the salesperson, NO Thanks! Put a 8.1 engine coupled with an Alison then you'd be whistling my tune. That sucker weighs 8,000 pounds or more empty. Depending how many deadly batteries you care to pack.
