A lot of people have bought them used with miles on them so it would be great to see who has PUT the most miles on their T4R.
Should never have an LBJ failure if you're maintaining the truck properly. They're wear items, it's up to the owner to change them before the failure.
Agree with you on LBJ, but no control over Head Gasket failures except for maybe good coolant/oil maintenance. Even then, no guarantees.
