Find one with a duramax. They are better engines with more pulling power and 3:73s. 06 was a great yr for the duramax too

My uncle has an 01 6liter and he gets about 11mpg with 3:73's. He is trying to sell it because it is too much of a hog and he doesn't see any advantages over a dmax.

What makes you want a gas over a diesel engine?? As far as I'm concerned if you want a 3/4 ton truck they shouldn't even offer them with a gas.

My driveing 75 % of the time is drive any where from 1/2 up to 5 miles and cut it off unless I go to town . With a dollar a gallon difference in the gas and I know a diesel is made to run and figured I would do more damage the way I drive from one farm to the next .I have 7 tractors and a Tractor trailer so I know about them . I don`t even like to crank one up unless I`m going to use it . Would love to have a duramax but I may pulla horse trailer a couple of times a year on a long trip but go most every weekend 15-20 miles . I know the milage sucks on either of them but it will be 20-25 dollars more everytime you fill up. If I could fine a 06 or backreasonable on the duramax I would consider it . All ways been a chevy man but I looked at the new ones and I hate the interier design . I have 2000 1500 that I bought new and it does a good job but was just wanting to step up a little.
Thanks

I see your situation now and I defenitely understand why you wouldn't want a diesel what with having to leave it run all he time. Because I'm so cheap in your situation I would almost keep your 1500 for your daily driver and pick up a mid nineties 2500 to pull with. I know I am failing miserably at answering your original question, but I don't know and it's not looking like anyone else has anything to say

You will get better MPG's with the 3.73's. The 4.10'sare good for towing. The only reason I would go for the 4.10 gears is if all I did was tow or if I did allot of drag racing. Or I might go with 5.73 for drag racing.

I had a 2005 2500HD 4x4 with 4:10 rear end . I got 13mpg with the stock 245/75-16 tires. When I put 265 tires on it I got 14.5 mpg (not towing or hauling anything). Now I've got a 2008 2500HD 4x4 with 3:73 gears and the 6 spd. auto tranny. The '08 doesn't feel as gutsy as the '05 and is shifting up and down all the time. Mileage on the '08 is only 12 or 13 mpg. I kinda liked the old truck better.

I have an 02 Suburban 4x4 with the 8.1l; allison and 4:11 rear end. Around town I get 11mpg; on the highway loaded or unloaded I get 14 at 70mph; though if I push it harder or hard driving around town (hard acceleration etc) I'll drop down to 10mpg. Like scotstr said; depends on what you need the rear end for; if you don't need the 4:11/10 then get the 3:73. I like my engine/tranny combo cause it has the power of a diesel without the smoke/noise/or at this point higher fuel prices; it all runs on 87 oct gas!
