Three-way refrigerators have three power sources: propane, a 120 volt AC electric element and a 12 volt DC element. This type of RV refrigerator is a good choice because it can operate at any time, including when traveling on the road. Three-way fridges are convenient because of the power options, but they can sometimes be less efficient than other refrigerators.
You can use a standard compact refrigerator in an RV with a power cord adapter. The RV must be connected to a power source to use this type of refrigerator, but it is a good option for RV owners who are staying long-term in one place, such as a campground or RV park. Compact refrigerators are not specially made for RVs, so they may not be the best option, but for anyone on a tight budget a standard compact refrigerator will usually be the least expensive replacement option.
A 12-volt mini fridge is a good alternative to a cooler when camping or traveling. Often this type of refrigerator is small enough to carry around without much trouble, so it is a good option for someone who enjoys taking short day trips to go fishing or to the beach. Larger 12-volt refrigerators are available for RV owners who want to place one permanently in their vehicle.
Refrigerators powered by propane gas are a popular option for RVs. They can run without a connection to an external power source, so RV owners are not restricted to campgrounds with full electric hook-ups. Campers who want to stay long-term in a remote location should look into the propane refrigerator options made specifically for RV's. Many propane fridges are large enough for most campers' food storage needs but only use a small amount of propane to run.
