Anyone know about what can be expected for MPG with and extended DRW that has 3.55's and an auto? This is all highway driving going 70-75 MPH?

 

I have the same truck. Around town in the summer months I get about 15 to 16 mpg. Highway traveling at 65 to 70 mph around 18 to 19. If I keep it at 65 I can eek out about 20 sometimes. Considering the weight and the fact that it is a brick on the highway, thats pretty good milage.

 

2X or 4X???

 

Mines 4x4. 2x4 will do a little better

 

2WD

 

22-24 if you keep thr RPM's around 2K, I get 20-22 with my 2500 4X4-Thats highway only.

 

2k is roughly what speed?

 

2000 rpm on mine is 70 mph

 

Only way you're going to see 22mpg on a truck with training wheels is to keep it at 60mph with no hills.

I'd plan on more like 19-20 max, considering it's only 2 wheel drive, if you keep it under 70mph.
(actually, on a dually that is 4 wheel drive )

If you go 75 the whole way, it'll drop like a rock to 12-13mpg.

How many gallons will it hold?

 

35 gallons

 

$200 in diesel plus tolls. Hmmmm

 

I don't agree, I have driven a 96 4X4 dually at 2000rpm on many occasions and have netted 20 MPG with 4.10's

 

I think 12v get inherently better mileage than 24v.

 

I get 24-26 on the highway with mine at 70. 19-20 at 75.
