Strong opinion here. Anytime I make a modification to my 4Runner I always keep my trips to Baja in mind.

• Don't bob the bed. You want the storage. You might also want to consider the need to sleep back there. Cover it.
  
• Extra fuel. An auxiliary fuel tank is a must. Extra 20L cans are a good idea. I carry 35 gallons on-board when I go to Baja (17 factory tank, 14 NMMP tank, 5 on the rear bumper).
  
• Dual batteries are a must, even if the second battery just powers accessories.
  
• No tire larger than 33". Install a lift to match.
  
• Lower gearing is a must.
  
• At least a locker in the rear. ARB or electric are good choices.
  
• You must have a full size spare. Mount the spare on the rear bumper. The Marlin bumper is good for crawling, not exploring. Look at bumper designs from Slee and 4X4 Labs for ideas. They don't make them for minis, so plan on building your own, or getting one built.
  
• Winch, you must have a winch to get your butt out.
  
• Hi-lift jack. Get one and learn how to use it before you get stuck.
  
• Communication. Get a CB radio. Better yet, get a HAM radio license and a dual band radio. My ham works where cell phones don't.
• Consider a 12V fridge. Sometimes ice sucks. Run it off the second battery so you don't kill your starting battery.
