Good points, and kinda the same thought process I had. I knew I would have one chance to prove to the wife that this sort of trip would work, and I wanted things to go smooth. I had worked up to this with weekend trips, but never anything over 1000 total miles.
This truck is my DD, which actually helped me feel confident in it's reliability. If you don't drive it, how do you know it's reliable?
And the Fridge was certainly nice... but I had trouble with my 2nd battery halfway through this trip, the wiring gauge I used to charge the rear battery wasn't big enough, and the fridge eventually surpassed the charging ability of the system. Luckily at night the fridge didn't climb in temperature that much, during the day it was powered by the alternator. So, my point is that there is something to be said for the simple reliability of a ice box.
