Last hunting trip to eastern Montana, I had the mid-size freezer in the back seat of my extended cab Ford F350, along with my two black labs. Bounced around some rough roads, but the duck and pheasant shooting was great. I can tell you the freezer holds at least 12 pheasant and 12 mallards (possession limits). They stayed nice and frozen for the duration of the 2-week trip.
The power came from the truck's lighter socket, from the small solar cell on the travel trailer and/or and occasional 120 volt AC outlet. The ability to use whatever power source was available was great. Everyone ought to have one of these gadgets!
