Im new here guys, one of your moderators Rogan told me to get on here and ask question. So here we go.The truck is a 03 2500, with 288k miles as of now. For the past couple of weeks, not every day, it has been dead and had to be jumped. The times it has happened like this morning it was 30 degrees outside, so not that cold. Im in Texas, so cold doesnt happen to often around here.The batteries have been tested, and said to be good. When there on the charge box everything cranks up fine, so to my thinking the starters fine also. I dont know much about this truck, as im more of a Ford guy (forgive me), so im at a loss of where to start. All my knowlege on other cars has got me always going back to the batteries, even though they supposedly tested good. Now once the truck has been started up from the jump box, its starts as normal from then on out. Like I said this has happened maybe 3-4 times, and its not an everyday things.Like I said:2003 Ram 25005.9 cummins288k on the clock2wdAuto TransAll stockAnd never any major problems since new.Any input would be helpful.Thanks.

The OEM filtration improved in 04.5, but the bodies are the same. The tips are different, but that has to do with the pistons. The 6.7 bodies are the improved ones, and the current 5.9 bodies are stronger too.
