Besides all the great advice given, if you find yourself dry camping a lot, no matter what type of battery you end up with, get a good quality battery monitor. I'm a big fan of the Victron BMV-712, but there are other options if you want something less costly.

Do you have one of those 12V 120V Refrigerators that don't use propane? If so you need a lot more battery capacity.

There must be something wrong, but I think you already know that. We bought our "new to us" 2016 Solitude in early 2017. That summer we went to our favorite Michigan State Park for vacation. We had the original single battery. Two days before we were supposed to leave there was a horrendous thunderstorm that knocked the power out. We immediately switched both the fridge and the hot water to propane. We ran only enough 12 volt lights to play cards or read. The roof vents were open but off. Here's the strange part. Our refrigerator didn't start beeping for 36 hours, at which time I connected to the vehicle to charge somewhat. 12 hours after that I had to connect to the truck to be able to run the hydraulics to hook up and close the main slides.
There must be additional loads on your battery, or a problem with you inverter not charging to full capacity. Just remember that the battery kill switch does not kill everything!Frank and Char + Maya, Newport, Michigan. 2016 Solitude 379FL/2006 F250 6.0 diesel w/dually conversion. 4th rain-sense roof vent, two ceiling fans, Kodiak disc brakes, Carlisle G 14-ply tires, Water Miser x2, final dump valve, water header tank, fridge cond fan switch, outside range exhaust, elec hot water anode, filtered drinking water, triple battery box,

Agree @Redapple63 --- My finding is that this battery is a 90amp hr batt. If say the refer is rated at 500watts running on 12v that alone is 41.7amp hours a day so there inlays an issue. We have 2 golf cart batts (6v ea.) and rated 225amp hours per battery. We either fire up the generator as needed or let the solar with inverter take care of our needs.

Your math is wrong, but you stumbled into being close to a reasonable answer. Your refrigerator probably draws about 2A when running on propane, which is a little less than 30W. That translates to 48AH daily.
You also want to be aware that with batteries in series, the AH available from the pair is the rating of an individual battery, so you have 225AH total.John & Kathy
