HuntAway

After reading the "After the shot...Shipping your elk" thread, I got to wondering about power inverters and taking a deep freeze with me for a hunt. My questions are;

1. Would it work?
2. Would I have to modify my truck in any way? i.e. new alternator, extra battery etc.
3. How much de-boned wrapped meat,does an elk yield?
and finally...
4. How big would my freezer and by extension the power inverter need to be?

Any thoughts or ideas.

Thanks,
