12k lb winch works fine for us. Hasn't failed us yet. And we use our truck and winch. But we carry 80ft extension rope and multiple snatch blocks. Much more flexibility for recovery than a mondo winch. Plus, way less weight and money. Although... I guess if you spent more cash in your pocket that would save some weight.
LED lights are sweet but not worth it. Can easily wire AUX lights (to factory switches) that are far superior and less money. We did look at doing a LED light swap but much too expensive and involved.
Keep in mind the front factory LSD is a clutch style unit (not torsen - gear drive) meaning it won't give 100% traction to both tires where one tire has full traction and the other does not. Definitely better than nothing but not ideal. Plus, you can't disable it in the snow/ice which can lead to interesting steering characteristics.
Tremor package is definitely nice! Especially from the factory... Glad Ford is offering more off road oriented configurations.
If you really want to save money...
You can't beat the XL model with optional vinyl floor (no carpet), vinyl seats (great feel).
4.30 gears are a couple hundred bucks with factory rear elocker.
Skid plates are a hundred dollars.
Add a front OX locker (wire to factory AUX switches) and you have a fully locked rig for relatively cheap.
