Personally.. You should of bought a Jeep for that type of outfitting.
A truck has no business going deep in the backcountry, IFS complications, lack of decent traction (its really a 1x1) unless you get full lockers front/back.
I used to own a couple trucks and also a '10 Range Rover sport (full independent, and probably the only exception).. and I can tell you from experience. I own a '13 Rubicon unlimited now, and it will go ANYWHERE without a question, equally as off road capable as the RR (Elk trip Northern BC '10 river crossings etc) without the $$.
Jeep now has the improved engine (bolt on +100 rear wheel hp for $5k) will give it LS1 power from a V6, solid axles, true 4x4 posi (lockers front/rear)...
The Jeep is an AR on wheels... the options you have for after market stuff is mind boggling. Unless you need the box specifically for carrying a 1000lb load. my argument is invalid.
NEwayz could go on on .. just my 0.02
