Anyone having electrical trouble with the 2003 3500 chevy? There are at least 10 of us within 200 miles of one another having the same trouble. Warranty is one thing, but when the system fails with only 1500 miles on it -- Chevy becomes a very undependable rig. Yes I know I should have bought a Dodge with the new Cummins -- but I didn't. Doubt they will trade with me now. Got any suggestions?
