When I was in the Army, I had a standing challenge to anyone:
I will keep my Jeep in 2WD (open diffs front and rear) and follow you anywhere with their Jeep in 4WD.
Uphill, Downhill, mud, sand, fording rivers (except once, buddy went in water deeper than intake, I didn't follow and he didn't make it out of the water ((well he did, the Jeep didn't)))
These were M151A2's. No computer, no ABS, no Traction control, no radio, no ignition key, 4 speed, no synchro 1st gear, 4w independent suspension, no roof, no doors, no pollution equipment, 4cyl-no horsepower to speak of (top speed about 55-60MPH), no handling-you could overturn these in a heartbeat.
Never lost the bet.
Technique over technology.
You don't need 4wd. Just makes it easier to get in over your head.
