"really hilly where i am so the 4 wheel really gives me added confidence in keeping the frontend down. "
Two things to remember:
Wet grass is slick...that MFWD won't help too much if you're slipping sideways or down the hill. Use good judgement before you operate on those hills! Walk 'em first if you need to... No task is that important to work in an unsafe manner.
These non-synchro transmissions don't shift when you're moving. Whichever gear you select going up or down slope is the one you need to stay in. If you do need to shift gears, make sure you don't pull it out of gear until you're stopped. Otherwise, you may go for a rather wild ride in neutral. Better to select a lower gear to ensure you've got the power to get up the hill and to ensure maximum engine braking going down that slope.
