I'm assuming you have a combination 4 pin & 7 pin on the bumper. I have that and the factory 7 pin in the truck bed. For the TC I use the bumper connection. I use one cable tie to secure the cord to the truck behind the bumper. If I use the in bed connection I can't reach it with the TC loaded. If the in bed truck connection gets loose I would have to jack the camper up to get to it. Not much chance of that ever happening though. But my bigger issue is Ram trucks do not isolate the truck battery from the camper. The camper can drain the truck batteries. (I've heard). So I use the bumper connection so that I can unplug if I'm doing some extended dry camping. I've never been in that situation, but you never know..
