Residential Frig / Dry camping

Buenos días Arturo. In your case I would suggest the UPS approach. Let me tell you how we do it when on questionable power. On both our big coach and little coach (the one you remember) we have it set up so if there is questionable power and maybe only 10 or 15 amp service available we can operate internally with perfectly regulated 117 volts. The coach has two inverters both sine wave. (The little coach only has one). We have a separate independent 40 amp charger that gets plugged into shore power directly...not through the coach shore cord. It charges the batteries constantly. The batteries feed the inverters that power the coach through your normal system. You probably already have one inverter and really you may not need the second one but we added it so there were a few more circuits on inverter. Remember, the coach thinks it doesn't have shore power so it is running on inverter mode. No special wiring. The additional converter will never draw more than about 8 amps from the shore post and the converter tolerances can handle quite high or low voltage on the input. Of course, air conditioning is out with this approach. Not sure how much you use AC.
