re: Lift - anything over 2" is reducing your articulation and effectively reducing your actual off road capability
re: tires - not sure on the 150, but on the 120, 285s are not at all worth the extra work/energy/cost to make them fit. I would rock 32s (and I do) That extra ½" of axle clearance won't make a difference off road, but you will lose 1-2 MPG, you will have a spare that doesn't fit, have to chop your body mount remove front fender plastics, etc. Not worth it IMO.
re; lift kit - unless you plan to do A LOT of serious off roading, you don't need reservoir shocks
re: "poke" - Skateboard stance is for hispanic dudes in full size Chevys who drive 100% pavement and say "bro" every other word, wear flatbill hats that match their shoes, and don't care about their paint-job. When I see trucks like this I think "wow that person is a god damn moron"
