You'll love it.
The only down fall to mine was driving in sand.  Stock "lo" gears were perfect!
I drive most all of the sand now in 2wd "Hi" now.  Only one hill I can't do that with and it's only by a couple of feet.  I just can't make it to the top???
So, 4 lo, locked, and 6 grand, I'm always over the top!  Well, almost always. ÂÂ
 Every once in a while it will take a second try.
I love sitting at the top of "Test/Challenge Hill" and watch all the other trucks "try" to make it up!
