"All the scenarios so far have not demonstrated the superiority of a 4x4 in a bug out situation."

I am assuming that in case of an emergency our road crews are not going to be running the snowplows. Therefore, around here whoever doesn't have 4WD and chains ain't goin' nowhere. 2WD will be sufficient if the disaster is kind enough to strike in the summer though. <img src="/images/graemlins/cool.gif" alt="" />

My bugout vehicle is a full size 4WD Dodge pickup with shell and chains, pulling a 19' trailer. My backups are Yamaha 4WD ATV's.
