I just bought a 1999 Chevy Silverodo 2500 with 6.0 engine and 4.10 gears. I normaly pull a small 15 foot cargo trailer behind it. I was just wondering if anybody has 3.73 gear and what fuel milage they get with it. Thank you for your reply in advance.

 

I don't have a 6.0 but I have the gears. 5.3 v8, ext cab 4X4, 3.73 gears I get 16 city and 20 highway.

 

i have a 2000 model obs 2500 series, 350 engine, with 3.73 gears.

I get 14-15 on highway and 10 pulling a 6K trailer.

I pull in third as I do not have a tow mode on this truck.
