Thanks for all the quick reply's. I'm starting to realize this dealer did a poor job at explaining everything to me and making sure everything was set up correctly. It dawned on me this morning that yesterday he had the shore power attached during the walk through and we never actually tested the battery, so now I'm assuming the batt was dead already when I pulled away. I'm charging it now so I will test it in a few hours. My truck is a 07' ram 1500, I did some reading and I think maybe it can only maintain the battery not charge it. Is that correct?
