Those with a 2016 or newer F150 (had one but now have a 2019) be aware its RV battery charge circuit cannot support accessories unless there’s an onboard battery that’s at least mostly charged. There is no fuse in the line. The line is monitored by the computer which cuts off the line if the battery is very low or not connected. Learned this the hard way when I picked up my TT after the dealer had had it over a month. Dead battery and with 7-pin plugged in, charge circuit was dead. Assumed blown fuse, but couldn’t find one. Called Ford CS which at the time (2016) didn’t know there was no fuse until over half an hour of searching its database. Now I carry an extra fully charged battery whenever I pick up my TT from the dealer. If the onboard battery is dead, it will not even reach from the truck.

Been there, with batteries that couldn't put out enough volts. I tried that trick too, ie, hooking up the TV, but it just wasn't enough. The Lippert six-way leveler system needed at least 12.8V, and the TV couldn't do it. Had to buy new batteries, as the three year originals couldn't be fully charged enough.
Channging Battery Type?
