The only problem you may encounter is with your approach angles on your front and rear bumpers. You don't want to get either hung up on rocks, especially with a loaded bed.
I take my bronco wheeling, and while its as small as a full size can get and still be a full sized rig, I can take it anywhere a lifted jeep can go, even with the factory stock suspension.
With your setup, the only mods I'd offer up would be either a locker or LS differential in the rear axle and anything else should be limited to cab comfort and gadgets. Things like a power inverter for a tablet or computer and GPS. Stuff along those lines. Anything else would be a waste at this point, until you've tried your rig out a bit to see what it really needs now
