Ok, right now I have a 2001 4x4 TRD Access Cab Tundra. Only modification is the bedliner. Here's what I intend to buy this week, let me know if you guys see any problems or have suggestions...

Wheeler's front coils w/ limiting strap
Wheeler's 16x8 black steelies
285/75R16 BFG All Terrain KO's
ARB Sahara Bar
Warn 10,000lb Winch
Skidrow skidplates (all three)
Leer Hi-Rise Bedcap (I realize it's not an off-road mod, but hey)

 

Sounds like that will be a pretty sweet Tundra. Just wait a few more months and you will have ARB lockers in and some sliders and some lower gearing, then i a year or 2 itll be SAS and crawler t-case!
