RE: Power Inverters for a Freezer
Every Wal-Mart down in these parts sells dry ice. Not sure about up Canada way. I bet there is some to be found along your way without much difficulty. We took the motor offan old chest freezer and take on our trips. With most of the weight gone, it only adds bulk space. We fill it with gear (okay, boxes of beer) on the way. Beer is gone on the way home and the kill has replaced it. I am sure there is a formula for how much dry ice to place in container based on the amount of meat to cool.
I can tell you for a fact that we placed "cooled" elk meat (2 quarted elk) in our "cooler" when leaving camp in the Rockies, placed 10 lbs of dry on top of it (wrapped in newspaper) and then driven 700 miles across the plains in temps you won't see in your part of the country.Didn't remove the duct tape around the lid until the following morning, and found the meat partially frozen when we did.
Just saying that is far cheaper and easier than messing with generator and plugs and such.
Good luck and let us know what you choose and how it works out for you.
