Even though I shouldn't ever need to charge the camper via the truck, I'm going to shoot for the largest wires available.
The reason for not adding another bed receptacle is that it's a new truck and I'm lazy.
You're probably aware that no matter how large a wire you use from the 7 pin at the bumper up to the camper, the stock, 12V constant wire within truck harness going to the 7 pin outlet is at best, 16AWG. Far too small to provide any meaningful charge except over a period of 4,5 or more hours of driving depending on the battery's state of charge.
You're probably also aware that the camper jacks need to have a FULL battery(s) in order to lift and lower. Should you find yourself out in the boonies (or even just the side of the hwy), or in a situation where the camper needs to come off of the truck with deeply discharged batteries and no ability to quickly charge, you'll be hating life.
