trading off dually

[biff101]

looks like I may be in this tomorrow. Test drove it today and works great. Gets 20mpg over the 14 mine gets. 4x4; Stacks and 35's

I like your dually better those stacks look like they are ridiculously over sized. Make the dually a 4x4.

The guy works at the local Peterbuilt plant. You can guess where those came from. I am geting the stock stuff so they may go pretty quick. I dont have to have the dually as a 4x4. It works great in the snow and mud up north. just want mpg for next years work schedule.

here are the stacks.

im partial to dually's cause i have one..the other truck is nice, not a fan of stacks (especially ones you can stick your head in). its a nice truck.. dont know know much about the difference in gas milage unless the gearing is different. gotta rem your trading two extra rear tires off , and instead picking up another 1,000 pounds woth of transfer case, and front axle. if it a nice truck, and you like it better than yours - than go for it if you think its worth it. but i think you might be a custom tune away from matching his milage - IF there even is a difference at all.

edit - and btw mine gets about 16 mpg with my 4:10's if i take it easy with it.

I have a superchip in mine,6637 and the downpipe to straight exhaust. I think with the 410 gears I will never get better than 13.

Yea I could never get much better than that in my 99 f250 4x2 with 4:10 gears.

i have the 6637, no cat, no muffler, no chip and like i said, i CAN get 16 mpg if i try with my 4:10's . its not all about having a high gear for mileage. the lower gears in my 4:10's allow the truck to move itself with less effort - if your milegae is that bad then i suspect somthing else may be hurting your efficiency.

either way - both trucks are nice, and i wouldnt be so quick to trade something off just to pick up 2 mpg. any gain in milage will be quickly offset by a steep repair bill from an unknown problem.. if youd like to trade, id say do it cause you want the truck - not to pick up mileage
