So Fishy, is that a no "your not going"? :-D
I completely understand where you are coming from. My truck is pretty capable. The other vehicles and skillsets with me determine how hard I can play.
There are tons of things I'd like to add. A flatbed with roll cage for one (why I didn't go to Moab). A winch, air, both are on the list.
With regard to survival, hear ya. Ever heard of "prepping" :-)
