I picked up a double cab off road at the beginning of June. So far I love it. I have about 2500 miles on it already and have taken it on a few camping trips and road trips. I haven't done anything to it so far but it has really amazed me how capable it is stock. The rear locker is a game changer off road. I have been on some trails that I shouldn't have been on but it walked right up them.
I did just pick up some Relentless Fab skid plates yesterday. Front IFS is aluminum then a trans/transfer case steel one which should give me really good protection underneath. I hit the stock skid plate (if you can even call it that) lightly on a couple rocks and it folded up like a piece of paper.
Besides that I'm planning on some sliders, front ARB, and a 2" lift. I don't really think the truck needs anything else to be really capable off road.
