Ammonia versus Compressor Fridge...
After all the talk about Danfoss compressor fridges and how much better they were than the old school Ammonia Units, I decided to 'fiddle with mine and do a long term test using a remote digital recor...

our current camper is a 2013 model 1806 real lite. It and our previous three campers had the adsorption refrigerators and it was luck of the draw as to if our food stayed cold. It was common to reach 50 degrees plus when driving on hot days. I have now installed a model TF65 12v/110v compressor fridge from truckfridge.com , they build refridgerators designed for big rig sleepers and are located in kentucky. Also available through Amazon. Its just now starting to heat up here in ohio so a true test will be at least a month off but so far only issue has been finding a setting for the thermostat that works both in the day and cold nights. I leave my camper installed in the truck with the refrigerator running 24/7. So far the battery has not dropped below 12.4 volts after sitting for 3 days. When I drive the truck the dual alternators in my Dodge keep the battery charged over 13 volts. The unit I installed switches to AC automatically when available. I did install a switch in the 12 volt feed to shut off if needed and it has an auto low voltage shutoff. I expect to need a small solar panel when the hot summer arrives but for now its perfect and only cost $699. I installed a agm 105 hour battery and digital voltage gauge also. The big problem for me was the old dometic unit was to wide to fit out the door for removal and required surgery with a saws all. The TF65 is the same capacity as the old dometic but a physically smaller size. I was able to install more storage in the one foot high space left above the install. I have an indoor outdoor thermometer with min max history to keep track of temps.
