Battery maintenance

Good luck on your new RV. Sounds like you are going camping at least every other week. Being a new camper you probably go in it at least once a week anyway to add things to it, so just check the batteries with a volt meter when you enter. You should read 12.6 + volts if they are fully charged. You will get an idea of how fast they will self discharge. Do you dry camp or go to FHU sites? If FHU they will charge when you plug in. If you dry camp fully charge them when you return home. Batteries will self discharge over time but new batteries like what you have will be fine if you have a battery disconnect switch and use it between your camping trips. I charge mine up in Nov and they sit over the winter with out a charger on them. They sit a month or so sometimes in the summer without a charge. If you post what charger you have you will get more detailed answers. Most batteries die from under charging and the plates get sulfated or overcharging and not checking the water levels.
