Bad Ground ?

I have a 2005 3500 4x4 towing an All American Sport 5er toyhauler. With the trailer unhooked but with the 7 way light cord plugged into the truck , I seem to have a feedback in the tail & marker lights. With the tailights and the left or right signal on, I get a dim flash in the opposite side tailight. The rear marker lights also flash dimly. It sounds like a bad ground to me. I checked all the trailer light grounds with no success. I had the truck checked by a Dodge dealer and said it was ok. I also hooked my truck to another 5er and the same condition persisted. I also attached a temporary ground between the truck and the pin box, still no success. I'm convinced the problem is in the truck and not the trailer, but where ? Any help would be appreciated, thank you.
