A FW is also easier to hook up/disconnect, than a TT. I don't know if your boondocking includes trees, but that can be a disadvantage, due to the height of many FWs.
Your truck is very capable of carrying a FW. Like mentioned, you need to go by your RAWR/tire max rating.
IMO, the best hitch for the Ford OEM pucks is the B&W. You can get the heavy slider, not really needed, or the much lighter 3300 non-slider (my choice). It is adjustable up/down, ahead/back.
I would stay away from the Lite models, if buying used. Keep asking questions, there are lots of helpful people here. You will get varying advice though, that you will have to sort on your own.
