Good morning, new owner looking for thoughts. Thinking of putting a marine deep cycle battery under the bed along with a 600 watt convertor. Put a cutoff switch between the two so not to drain battery when not in use. My purpose is to get more nights of usage before charging is needed. Trying to avoid $329 battery pack that needs charging almost daily. Please don't worry about hurting my feelings. Frying my system is more important than my feeling. LOL
Where do you plan to vent the battery as it sits charging under the bed? Also, converter will likely make some sort of noise, humm or fan, so it may disturb sleeping.
