As far as my wife goes she wheels it just as hard as I do.
It is not a street driver for her, she has the tow rig for that. Any way off of that rant.

So it sounds like the install is not that big of a deal.

I think what I will do is put one in the rear for now since they are only $200.  And then ask for the other locker for my birthday.  
As far as drinving on the street in 4 wheel drive.
I live in western Washington and if our weather keeps up like it has I won't need to worry about snow or ice on the ground for a long time.

I was thinking of Going with a LockRite Locker? Any input on this.

i put my locker in the back and built it my self, well my dad a mech. for 20 some odd years helped me. the thing i see is a locker in the rear is far better, you always are going up hill when climbing correct. so instead of pulling your self up hill with only the weight of the engin holding you to the ground. the rear always has the weight of the entire truck holding it to the ground
