I just joined the group. I bought a 2003 2500. The previous owner installed a Banks air filter system and actuator rod assembly and Quadzilla gauges. Also is 4x4, Quad cab. Looking forward to suggestions on economy while towing. Gets 22+ driving 65 mph. I am a long haul truck driver, mostly driving in BC and Alberta from our base in the Sacramento, Ca area. Also looking to get a small toy hauler so my wife and I can do some traveling.
