Not too shabby. Mine completly sucks with the school traffic back on the interstate. Might as well be a 28mile commute to work with 400 red lights. I go the first 10 miles no prob at 70mph. The last 18 miles are nothing but 0-20-0 on the interstate. Ive been averaging 13-14.5. Depends on traffic. Oh but now they are doin road construction on the first ~7 miles. So these next few months are gonna suck!
But if i can get it on the interstate and cruise at 70 i can see 23-24mpg.

I just put 265/70/17 mud tires on the truck too so that dont help. Them dudes are heavy.
