Hi I recently purchased a 2001 Ram CTD QC 4x4 LB 5spd. I found this site while I was looking for the truck. The truck has 120,000 miles on it and I bought it off ebay in Dallas. So I don't know the history of this truck, as far as maintence. My questions are what should I do first to this truck? I drove it 1500 miles after I bought it, and it ran great. Mileage was only 16 mpg though. What are some good ways to increase my mileage? I've heard about an EDGE power chip, how good is that for an increase in mileage? Any other suggestions on what would be good ideas for this truck are welcome. I've waited 10 years to be able to afford this truck, they first came out when I was 16 and I've wanted one since. I'll take any advice. Thanks.
