Tracy,

Thanks for the kind words. As others have pointed out, I suspect that the only way you will understand how lockers and traction control systems work in an offroad environment is firsthand experience.

Feel free to email me offlist and I will put you in touch with some of the best offroad driving instructors in the business.

I'm not sure there's much I can add to Dutch's fine explanation of the advantage of differential locks.
