If you 23 U is like mine, the golf cart batteries will be too tall. They are a much better solution (I prefer the flooded cell due to price.) but you're likely to be stuck with paralleled deep cycle Group 27s. These are readily available at Walmart for about $85 each and replace them every 2-3 years.
Also, your store switch should be in the use position for the converter to charge the house batteries.

RV is 2017 Thor Chateau 23u with 2 house batteries under the steps.
They are 2 12V and I believe group 27 size.
We purchased in January with very low mileage (2730) so clearly it sat mostly unused. We have put over 4k miles on it since purchase.
With minimal use, (lights, water pump) batteries run down overnight with barely enough charge left to start the generator in the morning.
I have plugged in MH during the day to charge up batteries, unplugged at night, set use/store switch to store.
In the morning, I set use/switch to use and batteries are nearly dead. Only one led lights up on the panel.
Is something draining the batteries or are they bad?
Thank you.
