Would love to know how that happens, my 02 gets 14.5 on a good day. I bought a 92 250 extended people van for the 360 518 to put in my LilRed but I might just stick the whole package in the 88 long bed 318 904 if I can get that kind of millage.


Those 20 something mpg numbers were all rolling down hill in Colorado. No word on the uphill mileage. smile

Last November going to Savanna from Va I got 19.7 from my 06 3500 4x4 diesel @ 70-75 mph down ins 95, my 92 4x4 2500 diesel got a best of 23.5 on ins 81 going to Carlisle and back. Just can’t get the gasser that good.
