Well, I certainly didn't mean to start a shirt-storm with my idle thoughts.
But on further consideration, IF, (and that's a really big IF) i were to go dedicated 2WD, I think I'd most likely lose the rear axle and go full time front-wheel drive, with a beam axle at the back. If I ever wanted to sell it, it would make an ideal tow-behind for the RV crowd. Just lock out the hubs and flat-tow it.
I've enjoyed reading all the responses. This is my first Sammy, and I really plan on just keeping it stock and running as long as I can.
