Drew,
I think I ran 14 awg wire 12 ft for my fridge 1.5 years ago and have had zero problems. I know some of the guys on mud thought it was too small. I measured voltage drop in back and I was only losing like .15v. For all of my work cars I have just been using the rear power outlets and they are only 18 awg and still haven't had a problem.
Look at the main wire on your alternator it is 10-12 gauge and they were planning on 40-60 amps. Even the new stuff with 80-100 is only 8-10 gauge. So I think you'll be fine.
I measured the amp draw once on the fridges and it is 2.7 at compressor start up (highest load) it stabilizes at 2.2 amps.
