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.
