jaws,
Earlier this summer we also did a dry camping trip. Our campout was five days. Again - I have the same trailer as you. Your mileage will vary, but we got between 60 and 65 hours from our battery. (I had a second one on hand to swap out at that point, and if you can get your hands on one, that would really help ease your mind). I do not have the electric awning, so that is a factor that is different between yours and mine. If you have to raise and lower the awning several times, that will impact your battery life.
I only put about 25 or 30 gallons in my fresh water tank to start off with, and I did run out. I had to carry about 15 more gallons from a tap to my trailer to make it through our 5-day campout. Based on what you've said about your usage, I think you'll be fine on water if you start out with a full tank.
You do realize you won't be able to use air conditioning without a generator. Right? You also won't be able to use the microwave, and probably no hair dryer or coffee maker, unless you've got a pretty powerful inverter. If you do have an inverter that can handle these, you will run down the battery quickly.

After discovering the issue with the water pump, I wanted to confirm that we'd be able to last significantly longer when there isn't an unwanted draw on power. I recreated the steps we took to go camping last weekend at home the past few days. See below:
1. Fully charged battery and let fridge completely cool down while plugged in.
2. Disconnected shore power and turned on propane for fridge.
3. Ran the water for a total of about 10 minutes (to use the pump).
4. Used the electric jack to raise/lower the trailer a few times.
5. Had a few LED lights on for a total of about 15 minutes.
6. Extended and retracted the electric awning
My battery gauge is 4 lights on the control panel (4 lights = 100%, 3 lights = 75%, etc.). After the above, I was down to 2 lights (50%) and the CO alarm started chirping because of low voltage. I don't quite understand what I'm missing if you were able to get 60 hours out of 1 battery. Our battery lasted 20 hours and then the CO alarm started beeping so we wouldn't be able to use anything anymore because I would have to disconnect the battery. Any advice would be appreciated.
