In every RV there are many little culprits that suck on the battery even when unoccupied and everything turned off that has a switch. If the battery is already more than 50% discharged several times, it's in a weakened state and will go flat even more quickly. If your rig doesn't have a battery isolation switch, either get one installed or disconnect the ground cable so that it won't go flat again.
Should you find the battery is bad / old / under rated for your RV, be sure you get a deep cycle marine style replacement battery, NOT a car or truck battery. A car battery is made to give a huge jolt of amperage to crank an engine, NOT to slowly be supplying current over an extended period as an RV battery needs to do. Probably should be some info on your rigs electrical system that would help guide you on the replacement battery amp-hour requirements. If can't find anything, perhaps a 'rule of thumb' (guess) would be to add up all the fuses in your system panel and multiply by 2 and add 10% for the amp-hour rating of the battery.
