Check for loads when you disconnect shore power: 15 minutes to dead after disconnecting means you either have a heavy load or the battery was already toast.
You don't say what size battery it is but your winter use is likely drawing too much before recharging. TV/Lights/Ceiling fan could easily be pulling 20amps. At 6hrs, that would add up to 120amp-hr. For a single dual purpose battery, that's likely leaves it completely dead before you recharge.
Going below 50% charge on a lead acid battery typically does damage.
It's possible you have something on in the RV that is damaging the battery but my bet is the winter use.
