Trailer wire harness
Splitting the trucks 7-pin into both 6-pin TC plug and 4-pin trailer plug. What are you guys using? Fabricating a harness? Torklift's expensive splitter/extension? We'll be pulling a 6x12 enclosed, no...

I am using what came with my 2013 RAM 3500. 7 pin and 4 pin in the bumper and 7 pin installed in the bed. RAM came that way. Already setup. NO fuss.
Nice. If Ram is still around when I buy my next truck, I'll give 'em a look.

You could use one of these: http://www.etrailer.com/Custom-Fit-Vehicle-Wiring/Ford/F-250+and+F-350+Super+Duty/2009/20119.html?vehicleid=20091172147
it plugs into your factory wiring and replaces the factory plug under the bumper.

Sweet. Thanks. That's in the area of quick and dirty. It looks like I could plug that it into my existing, factory 7-pin and mount the new power block were I want. Easy peasy.
I've yet to source the components required to fab similiar, but the cost of parts and wire might be approaching their $34 asking price. The 4-pin pigtail (maybe 5 bucks) spliced onto my existing TC cord would do about the same, without the advantage of the nifty new power block, of course.

I spliced the TC harness into the backside wires of the 7 pin harness for indicator, brake and clearance lighting then soldered all connections and used Liquid Electrical tape to seal the connections. For your TC charging power run a separate line from one of your batteries through a Cycling/Automatic Reset - 30 Amp - Straight Mount Bracket Circuit Breaker(about $5 at e-trailer.com.)to the power lead on the TC harness. Mount the circuit breaker as close to the battery as possible to protect as much of the wiring as possible. You can get 8ga automotive primary stranded wire from most automotive supply place (Autozone,etc) and wet location crimp lugs from West Marine. Use a 7 Pole Flat to 4 Pole Connector Adapter under $10 bucks same place at the bumper.
What's the advantage of running another wire for the charging circuit? Larger gauge wire? Ford's factory ignition isolates the factory 7-pin charging circuit when you turn the truck off.
I guess amp draw/electrical issues haven't been a problem for those who have done this. I searched around in the Truck Camper sub-forum, but nothing came up about wiring a TC while towing.
Thanks for all the suggestions and input.
I could hack my factory 4 and 7-pin access doors, too, I suppose. My TC cord is plugged into 7-pin side:
