MPG

[Fast355]

One of my trucks just went on a trip half way across the country pulling a car trailer with a car in.
1994 GMC k1500 4l60 3.42 gears, stage 2 RV cam from amazon, true dual 2 in exhaust With glasspaks, 4 wire o2, EGR delete
Lean Cruise, fuel pressure slightly raised ( modded FPR when rebuilding TBI, not sure on pressure gauge from parts store failed never checked again figuered didn't matter since VE needed completly tuned anyway) 3 core Radiator, stant Thermostat,

Car probably 3000lbs
Trailer 2400lbs
Cargo, probably 800lbs

Gross guess 12000lbs + or -

Thought I'd share the fuel Economy and cost
Truck had good power climbing passes

Includes Idle Time also.

What do you think, good, bad, average?
1830 miles 10.8 MPG

I would hate to have your range. I get about that towing my TT with the 383 in my Express van. Difference is I have a 31 gallon tank. Really wish someone made a tank around 45-50 gallons for it.
