10.5-11, city or highway doesnt really matter. mines an all stock hemi lifted with tires also. hoping the predator will improve it some when i get one.

 

Geeez...i'm glad my truck is so little

 

2008 Reg Cab Short Bed 4WD with 4.7L, 3.55 gears and 275/60-20 tires.
It has 4600 miles on it and gets 14.5MPG with gas and with E85 it gets 12MPG with a mix of 50/50 Highway/City driving.

 

4:11 gearing
summer 11.5 -(14 highway) not toeing
boat on highway 13.5
winter 10-12
add one 4 place snowmobile trailer lucky to see 10
but don't see many trucks getting much better pulling a 4 place trailer.
Diesel might see 12-14.

 

Very nice rig btw, i think dodge has the best looking RCSB trucks.

 

Recent road trip: trip average -- 14.5. Lotsa city driving in unfamiliar surroundings and 80+ on the interstate. That's pencil-and-paper, NOT by the computer. The computer showed 17.8 on the interstate; flat ground and no wind.

 

08 1500 4x4 hemi quadcab all stock with 6400 miles on it...i get about 14 in town and 19 hwy at 68 mph.

 

8-9 pulling the 30' loaded travel trailer w/o overdrive
