[QUOTE="kleake, post: 1529691, member: 25987"] Sounds like an issue but driving speed, head wind, etc can really effect it. I have GH, exhaust, manifolds, pipes, etc. Empty at 70mph I get 18-19mpg. Push it up to 75mph and it drops to 16ish, headwind and it will drop a little more. Pull almost anything and it's in the 12mpg range. 36ft camper with boat behind and its 9mpg but that's a 25k load. These trucks really like the highway with minimal drag, but it doesnt take much to cause a drop in mpg. I'm not sure how much your topper effects it. Sent from my SM-G960U1 using Tapatalk [/QUOTE]
