None do unless you have a 3 way fridge. GD uses 2 way fridges. Propane or 120V.
You would have to install an inverter to get it to run off the batteries. Which means you'd need a transfer switch so you can switch back to 120V when on shore power.
Why not just use the propane like everyone else does?
Actually, they're putting 12-volt compressor fridges in the Imagine travel trailers now...

Probably it is cheaper, being much simpler. Has a bunch of upsides (more interior space, theoretically more reliable, safer, less finicky about being level) along with the downside that it'll drain a standard Interstate 12V deep cycle battery in under a day (and it's a little noisier than a propane fridge). So they have to pair it with the solar panel, which they can then point to as a premium feature. All the while the capital costs probably didn't go up much at all, but the consumer is willing to pay a little extra.I see other brands are offering 12V as well. Wonder if it has to do with lack of parts for Norcold or Dometic 2 ways?
