Down and dirty solar question.
Not terribly math savvy . But, will this system work to dry camp? Let's say, run the microwave five minutes per day (1100 watt), make a pot of drip coffee per day, run the water pump. And reasonably ...

Other than running the microwave or coffee maker, you might be OK to run a few lights.
However the 55 AH battery will not supply the 150 amps required to run a pure sine wave inverter and the microwave.
If you just want to run the coffee maker, then a 1,500 watt modified sine wave inverter might only cost say $200 or less, and would still require 4 golf cart batteries, to supply 1,200 amps to the inverter while making coffee.
Each of my golf cart batteries are 67 pounds, and what you have is probably only 30 pounds max, so much less storage than you will need to run a really large inverter.
As far as the solar panel, 40 watts is not enough to even keep up with the CO and propane leak detectors, let alone anything like the furnace.
It would take a 120 watt solar panel to produce 35 Amp Hours Daily to make up what the CO meter, propane detector would use, and run the refrigerator.
You might want to look for 12 volt 'nominal' panels here. SunElec.com
Then get a 20 amp PWM controller, and mount it to the roof with 2" angle aluminum. Run UV rated grey wire from the panel, down the roof vent behind the refrigerator, to the controller, then to the battery.
For dry camping, I would recommend at a minimum one group 27 or group 31 battery. In reality, a pair of golf cart batteries will run the RV for a long weekend without recharging it, but not a lot of accessories. With a pair of golf cart batteries, and a 120 watt solar panel, you can go weeks at a time without recharging, providing you are using LED lights and not to much else.
Good luck,
Fred.
