Thanks guys. I can see an RV tech mistaking the truck not charging if there is a delay, especially if they just start the truck and test right away and turn it off. They'd see zero and assume it didn't charge. But the irony is he said he worked for Ford.....so one would think......
And if it's a towing module, as mentioned in Jim's link, one would think that plugging in the TC would act the same as a trailer, to the trucks computer, if it's to do with the lights.
And I assume the truck charge wire going back to the bed plug is going to be dry spaghetti gauge. But r&r'ing it is something I'd be asking for written conformation from Ford that doing so isn't going to affect the new warranty! ;)
But I assume running a bigger wire to the bed plug is pointless if the wire from the plug to the camper is too small as well. Heck, maybe the plug itself is a choke point. But that's a chat for a separate post.
As for the BMS. That had a bit more logic to it. If the little on-board computer runs, it needs power. But given I hadn't seen any dismay expressed here or else where over it, I thought it smelled like a goofy statement.
Why is it people can't just be straight up? Seems RV sales guys are even dodgier then stereo type used car guys.
