I would start by checking for a missing relay and/or missing/blown fuse. I found the 2011 Ford F-150 owner's manual online with the following information. The fuse and relay that you'll need to check is located in the power distribution box. (Location: 9 - TT Battery charger relay) (Location. 21 - TT Battery Charger Relay Power 30A Fuse).
If there is no problem with your fuse or relay, then I would test your truck's 7-way connector for 12 Volt power. You can test that connection with a circuit tester like part # 4PTW2993. If there is power at that connector, then there may be a problem with the wire on your trailer going from the trailer side 7-way connector (11 o'clock pin, see wiring article) to the trailer battery.
I have attached a link with wiring information and additional details.
