Glad to see you getting the pieces picked up. I would get sliders and both bumpers from SA I can personally vouch for the rock sliders. You going for the 2" lift I would go OME HD not many choices for a 4" lift other than SL. His front wheel flares would look sweet to. I agree with the aux fuel tank I think you'll miss that option if you skipped it. Some wheels with a 5" back space or some spacers would look good. Maybe get a duel battery setup with a decent size inverter installed.
