You made it 10 years with a single inexpensive lead-acid battery. It does not seem you need to upgrade to a lithium battery and charging system.
Instead, do you have room for a larger battery or for a second battery? If not you should still do OK with a single lead-acid or AGM battery.
First step would be to do an energy audit. For most of us the big energy hog is running a furnace in cold weather. Otherwise you should be able to boondock for days with a single battery. Refrigerator controls and your CO/propane detector should use very little electricity. Same for the water pump. For many older RVs, incandescent lighting used a lot of power. If that is your issue, consider replacing all of the lighting with LEDs. New LED fixtures are inexpensive or you might be able to replace just the bulbs.
