I'm offered a 2002 8.1 2WD 49000mls avalanche and a 2003 5.3 4WD 43000mls avalanche.
The price is EXACTLY the same.
I don't think I'll ever ride this machine off-road.
What do YOU think is the best one to choose
How about 0-60 ? Can't find any data on that.

Unless you plan to do alot of towing, the fuel milage of the 2500 will kill you... 12mpg... compared to 15-20 reported mpg from club members with the 1500.
If you live in an area that gets snow, the 4wd will be an asset, even if you never go offroad, one winter with 4wd, you will never buy a 2wd again.
0-60.... they are actually the same performace... the 8.1 is a torque monger, and you would think it would be quicker, but it is not, as you are moving a heavier vehicle. This has been reported on the site, plus I kind of draged a member with a 3/4 ton last weekend at a GTG and well... outside of my response time being better, our avs pulled the same, I won only due to repsone time. All th8ings being equal it would have been a photo finish.
The torque of the 8.1L is a thrill to drive, but again, acceleration is not any different, and fuel economy will hurt your wallet.
Which one to buy depends on how you plan to use the vehicle, and which one you think you will be happier with.
oh, also the 1500 will ride smoother on the highway, although some say that the heavier 2500 is more stable at higher speed... boils down to personal opinion on this matter in my opinion (not ment to be a pun...)
Whatever your choice I am sure in the end you will be happy with either option.
