well i took the LT's and ORY off the truck.. and my mileage has already started going back up...
i thought that stuff was supposed to increase fuel economy (reading here on the forum)
i took it off because the truck was WAY to loud for my taste and it went from 16.8mpg@70 to 13.6mpg@70 with the LT's and ORY
i'm hoping the 4.10's help a little aswell.. if not i have 3.73's and if that don;t do any better i will put the 3.42's back in...lol
i will keep everyone posted on the gear swap

did you have it retuned after the lt and ORY installation?? if you didnt then thats why your getting worse gas mileage, you need a retune after installing lt's....
if youve already said you had it retuned, sorry, i didnt feel like reading through all the posts
and as for it being loud, run a 22" magnaflow and it'll be plenty quiet

ive got 4.10's and 33's, exhuast and k&n filter and the gas mileage is horrible on the interestate. its horrible around town also lol the rpm's are a tad too high, but then again mine is a 3/4 ton truck made for pulling/work.... i would say go 3.73's since you drive on the highway

UPDATE...
I INSTALLED 4.10 GEARS AND IT HELPED ALOT!!!
17.2mpg @65mph/compared to 16.2mpg
16.7mpg @70mph/compared to 14.3mpg
16.5mpg @75mph/compared to 13.4mpg
12.8mpg around town/compared to 11.1mpg
15.4mpg with my 4-wheeler in the bed/compared to 13.6mpg
i am averaging 14.3mpg/compared to 12.5mpg
but it actually feels like it slowed the truck down?!?!?
