Thanks to everyone's responses, your assumptions were correct. 12v fridge, ARB, edgestar etc. regular VHF/UHF mounted in the cab of my Duramax, so the run length is probably 4-6'. Nothing to exotic here.
I'm heading out on the Mojave Rd in a couple of days and was running wire to a 30w amp a friend loaned me to boost up my Kenwoods measly 5w. I had some 10g in the garage that I ran to a Blue Sea fuse block I pulled from my 4Runner. I was hoping to run the radio, fridge, and a couple of USB outlets for the kids off the block. I didn't think about the fridge causing noise, so I'll probably do a separate run when I buy a real radio.
Thanks again for the quick info.
