the xfe use light wheels better areo, and llr tires. maybe gears but they already run low.
i was able to pull off A 23 MPG trip(~100miles) in my dad 08 silverado crew cab 4x4 w/ factory 20's 5.3 auto., by driving with load and watchin the instant gas gauge, tried to keep it in v4 mode as much as possible.
,ost newer manual truck are rated lower than there auto counterparts.
but 20 is not bad for a pig
(my 98 4x4 truck weighted in at 3170lbs and is rated at 16/20)
20 mpg is what i am gettin out of my 09 v6 auto 4x4 excab trdsprt tacoma not driving easy
