Loaded or empty? My '16 gets 15 around town, but about 10mpg pulling the 5th wheel. It gets close to 20 empty hwy and 14-15 with most lighter trailers.


Don't know that he's ever had it loaded yet.... was a stupid purchase but it is what it is.


Seems like sometimes you just get a vehicle that's weird that way. We've got a 2010 Chevy here at work with the 5.3. That thing has never gotten better than 11 mpg even on the highway. We've had it in the shop numerous times and they can't find a reason why. We have two other similar configurations and they'll get close to 21 hwy.

Wife had a 99 suburban with the vortec 350 that would only get 9 around town. and 15 hwy. Others were getting 15/22. Who knows with some.
