Looks great and I'm really wanting to do this but I don't want to hurt mileage, towing, handling, or off-road suspension travel. 35" or 305 tires would look awesome but they seem to be 30-40% more than the stock 275s.
My truck is out in the desert a lot and I love how well it soaks up bumps while driving at speed in the dirt. Surprisingly, I've never had clearance issues on the stock suspension.
What I really need is to add a limited slip to expand 2x4 drive-ability in the snow and mud, and of course for decent doughnuts and burn outs.
