Keep your wallet handy for the car wash.
Get selectable lockers front and rear, or learn to drive without spinning the tires.
Buy some Intercos...get the 34x10.5-16 LTBs, Q78-16 Super Swampers, or 35x10.5-16 Boggers. Think about how you want to clear them...RCD kit, or sawzall. Decide if travel or height is more important, you can fit 35" tires many different ways.
Most important, learn how to drive. If you get the wheels spinning with the stock open differentials, you'll be spending an awful lot to fix what breaks...differentials, axles, cv joints...it's a mess. Hope your wallet is as deep as the mud pits, because it never ends.
Cmon over to the Offroad Forum...have a look at the build threads, picture and vid threads.
