Yea, I didn't explain that real well, was basically trying to compare having 4x4 to having a PSK or BOB or other survival gear, the kind of stuff you hope to not need but better to have it and not need it that to need it an not have it. It takes a bit less work when you have 4x4 and low range.
Years ago I didn't know what a PSK or BOB and never thought about having gear with me, now I don't leave home without my PSK or drive a vehicle without 4x4.
