Hi allI just found this Dodge forum and am anxious to learn more about my common rail. My 2004.5 qclb 4x4 replaced my 2001.5 2500 4x4 qcsb last summer with both being autos. We pull a 22 ft K2 bumper pull toy hauler loaded with our Polaris RZR. So far we've only made one 1800 mile trip to Utah and back and was very pleased with the performance and 11 mpg average, besting the old truck by 1 mpg but around town is not so good running between 11-14. But as I usually just use it for towing it doesn't matter much, I'd rather do better towing. Gerry
