-How long is the water in the tank good for.( How much clorox do you use)
-How do you drain the fresh water tank
-how do i protect house and car batteries. Do I plug into 15 amp with adapter or have an electrician install 30 amp.
-should i run a/c year round or put a dehumidifier in.
I drain my freshwater tank after every use. I pull all 4 drain valves and open all faucets so there is no vacuum lock and the system drains completely. I do not even use the air blower fitting to "blow out" the water as it never blows anything out as the system is well designed and the water runs out from gravity alone.
We use our RV about every month, so all I do is I installed a battery cut-off switch for both the engine and house batteries, so every time I park the RV I disconnect the batteries. Otherwise parasitic losses, like the hard-wired Propane/CO detector, will drain the batteries.
There should be no need for a dehumidifier or running the AC. I leave both my roof vents open.
