I'm looking at buying a 1995 Dodge Ram SLT 2wd long bed regular cab Cummins Automatic 3.50 gears for my wife and I just wondered what you guys thought it would get for highway mpg? It has only 94,000 miles on it and is a real clean truck but if it dosent do any better than 20 then its not worth our time. My 4x4 Duramax gets 19. What do you all think?

Company I work for has 3 of them, they all do 18-21 empty.

The old 12 valve motors did the best of any of them. Probably can get 22 at least.

A friend of mine had a RCLB 4X4 Dodge Cummins with the 5spd, i beleive it was a 99 or 2k. He got 23-25mpg average and he claimed a best of 27mpg, this was all open highway.
