      Thinking about changing fridge in our 2019 laredo from Dometic 3-way to all electric as absorption models struggle more as temperatures rise. If you changed your, what did you change to? did you stay with Dometic? If not what brand? All look pricey!

      ardvark, to me a compressor refrigerator is a great way to go but there are still trade offs when switching to a compressor refrigerator. You’ll need to increase your battery storage capacity and it will be prudent to add solar to that set up. In my 2002 Lance 815 I got rid of the 3 way after numerous melt downs of that unit and installed a Dometic CR1110 (2013)compressor unit. Here’s the YouTube link on that project Compressor refrigerator. My present TC (2020) Bunduvry has the Dometic CRX 110 compressor refrigerator in it.

      I’m a little late to your party, but having the above Dometic CR110 12 volt fridge is the ticket. With 330 watts of solar and all LED lights, there is now no worry at all about powering the Laredo. Sure, I can watch the Zamp solar charge controller as a spectator sport, but the whole thing even when using the heater, water pump, myriad LED lights, and fridge are completely transparent in use.I just wished I had gotten on the solar bandwagon a decade ago, instead of worrying about leaving the 3-way ammonia absorption on 12 volt overnight and having no battery the next morning.

      On mine I installed a normal household outlet close to my frig. – cut the connector strip between the 2 outlets – one I painted red and connected it DC and the other side to 110volts. And yes, I have installed a 110 volt frig in Travel Trailers. Thing is I like to have my frig running as we go down the highway – when stopped I hook to 120 volts, then
      change the plug over to 110volts. Have fun.
