We just bought last fall and most are switching to 12V DC fridges. They have been common in the marine world for years (can't use propane when the boat is heeled over 15 degrees).
There are trade offs.
Pros:
- Cools quicker when you start it up.
- The mechanicals are much smaller resulting in a much larger interior for the same size space.
- If at a campground on shore power, works fine.
- Eliminated a roof penetration as it doesn't need external venting.
Cons:
- Ours came with a small solar system from the factory but you probably need to upgrade it a bit if you are doing extensive off grid.(we've only done a couple nights off grid so far)
- Unknown long term durability...In theory, it should be fine but hard to say.
So far, we like it but with only 6 months of use, we can't speak to the durability.
