We're considering replacing the refrigerator. I've seen one of the larger gas fridge's in use at a camp and thought it worked well. I'm looking for info from folks who actually use these. How stable do they run ? Any issue with temprature swings ? How cold can the freezer section get ? Most importantly (and this answer will depend on local utility rates) How do they compare cost wise with a comparable electrical powered one ? I know I'll need a big tank for the gas. The less I can depend on "the grid" the better.
