I found a early/mid 90s cabover w4500 with a flatbed dump. The flatbed dump needs some electrical work in order to work. It has a 4 cylinder diesel with an auto. Anyways, I would like to know how many of you are running one, and how many mile per gallon you are getting. How many miles should I expect out of it? I believe it has around 130k. Anything to watch out for??
