Hi, live in western Colorado, not what you call flat land here. Have a 90 chevy 1500 4x4 with intercooled 4BT, 4500 trans and 3.42 gears. This truck has been in the family maybe 12 years, gets around 25 MPG on the average. We took it to Newhampshire to pickup another 4bt and pull back a 1500 lb trailer, at one point it got 34 mpg, I told the wife to go back through her figures again and it still came out 34, did it a third time no difference. Got home and it went back to 25, go figure, different blends of fuel, so many variables, who knows. Anyway I even put an RV fifth wheel in the back and pulled our smaller 2 axle camp trailer about 60 miles away and back, only had to down shift to 4th gear on couple of the big hills. We take it to Denver sometimes pulling Vail and Loveland pass and never drop below 4th gear but you gotta watch the temperature. This has been a great conversion. The 3.42 gears are just right as it will run 70 mph no problem, this truck is fun to drive and gets lots of thumbs up because it don't sound like no 350 chevy.
