12-volt freezer recommendations for road trips?

Sunfrost makes a good 12 volt freezer.

My ARB freezer can go pretty low to freeze anything. I have a second battery setup to run it not to drain the house battery. It has been bullet proof and runs thrift. Only downside is its high cost. But I buy the best when I can.
I don't think I would use it for fish. Smell would never leave. Engle also makes excellent units. There are cheaper brands, plenty on ebay.

I think they all run on 120v as well if you are overnighting  with shore power.

I bought an ARB 83 quart freezer.  It works great.  When I'm on the road I can freeze fillets, keep ice frozen, and re-freeze my "Tundra" Arctic Ice freezer packs.  I've been setting it at 0 degrees F, and it holds that temperature very well overnight, or when I'm out for a long day of fishing.  I'm looking forward to using it on hunting trips, when I'll set it at 33 degrees and put skinned and quartered game in it.

The first time I used the freezer, it didn't work when I tried to run it off my vehicle battery.  I was really bummed out.  When I got back from the trip I called the customer service guys and complained.  They explained that the wires running to the "cigarette lighter" power sockets in my vehicle were too thin to handle the surge of amperage when the freezer starts up, and the freezer was reading this as insufficient power from the vehicle battery, and was immediately shutting down to keep from draining the battery. They told me to get the ARB power cable and install it.  I did, and it fixed the problem.  The freezer works great.  So if you get an ARB freezer, get the power cable.

I bought the freezer from an internet retailer which offered a free remote monitor and cover with the freezer.  I probably would not have bought the remote monitor if it hadn't been offered for free, but it's really useful.  While driving I can just look down and confirm that the freezer is working and holding the temperature I set it at.
