Excellent decision to travel in the Fall. You will enjoy it!
We have a compressor fridge and only two 75ah wet cell batteries (75ah usable or maybe you can fudge a bit more, but not much). Let me emphasize that we used the advice on this forum to eliminate phantom drains and run everything on 12 only, never used the inverter. With good batteries that are freshly charged, we can go from 5pm to 9am the next morning never going under 12.2 volts (60% charge) and that includes several hours of lights, tv/dvr, and an entire night of Maxxfan or Suburban propane furnace depending on if we needed cooling or heating.
That being said, I'm in the process of upgrading to 200ah lithium batteries (180ah useable). The reason is my lead batteries are not holding quite a full charge, the need for checking/filling is a pain since it requires removing getting into the cramped exterior locker and removing tie-down straps and one cable to do so. Finally, they get dirty quickly, cause corrosion, we just want more reserve power. The lithiums will be inside and connected to a new 2000W PSW inverter that will run the microwave. The Wife is excited about that last one.
