This was the 3rd time this happened to the Dodge 4500 it began happening when we had less than 30k miles. The first few times 4 different dealers had no idea how to fix the problem, we even had an expert come from Dodge and ride in the truck for a day to try and duplicate the problem. The truck will completely stall and not move because the trash can for the new epa regulations does not properly clean itself out. we came across Blake Fullinwider at a Dodge dealer in Cisco TX and they were very aware of this problem. Most of their customers have these trucks and they were very familiar we spent 2k doing the upgrades he suggested and he spent another 7k in extended warranty work trying to fix the problem. We are usually loaded and roadside doesn't cover towing our trailer the costs and losses due to this issue would have put anyone out of business we have been taking money from other businesses to keep this thing going because we don't have a choice, its' more expensive to store it (we think). I have heard other stories from other truck owner that have gone thru the same problem and they are no longer in business because of these trucks
