I was considering adding such plug on my new truck, but from what I check factory puts them in rear corner of the bed.
That require to use cord extension anyway and with tall bed sides on newer trucks, you don't have access to the plug with camper on.
So what's the point?
I plug the extension into bumper plug, drive under the camper and plug camper cord into extension, securing the cables hanging on camper side.
Than lower the camper and I am done.
For years I've been crawling under the camper to pull bumper plug and in dry weather it is not a big deal, but thinking about my knees getting stiffer and stiffer with age and potential for camping in the rain, , the side cable connection is way better.
