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.
A couple of thoughts. First, my battery (after 60 to 65 hours) had totally stopped supplying power to everything. No electric at all. (I know - that's a bad practice for long battery life, but it's what happened.) At no point in this process did my CO alarm start chirping. I need to explore why. Maybe mine is not hard-wired?
Second, I think you should get a voltmeter and use it to measure your battery's voltage. The 4-light gauges in the trailer are really not much help. Mine show three lights (75%) after only a little bit of usage. A meter will give you a lot more information, and you'll begin a learning process in terms of how many volts to expect when fully charged, how many volts you have left after a few hours, when to swap out the battery due to low charge, and so on.
Third - I don't have the electric awning nor the electric tongue jack. You used both of those, and you say you used the tongue jack "a few times." My guess is that both of those, being motors, have quite a bit of amperage draw.
But still, you don't seem to be getting as much out of your battery as you should. It sounds to me like your battery is old and should probably be replaced.
Long term, you might want to consider solar. I've added a 100-watt panel to keep my battery as fully-charged as possible (with a 100-watt panel) on 4 or 5 day boondocking trips.
