Plugged or Unplug???

I leave mine plugged in long term as well, no apparent impact on battery life. However, you should check the water level in the batteries monthly. I have to rewater mine about every 9 months (Costco 2GC's). If the water drops too low bad stuff can happen.

I keep my fridge turned off but I use a mechanical dehumidifier to control moisture.

The battery will discharge in a few days to a week or so depending on how big it is without a battery disconnect switch or some type of charging. We leave ours plugged in to keep the battery charged, the fridge running ready to go, and the AC set to a high temperature to help control moisture in the summer.

With the RV plugged in, and chassis power switch to off positio, do the batteries still charge ? I have yet to turn the chassis battery switch to off ( other than to check it) and was just wondering while reading this thread.

The details of that would vary from RV to RV, particularly for the chassis (i.e. starting) battery of what I assume is a motorhome (rather than the house battery).

For the house battery, most commonly the disconnect will disconnect it from the converter and so it will not get charged when disconnected. This is not universally true by any means.

For the chassis battery, it may not be charged from shore power no matter what state the disconnect switch is placed in, or it may be charged only when connected, or I suppose it could be charged in either case. At least for lower-end motorhomes it's probably most common to not have the chassis battery charged at all via the shore power connection from the factory.

Drew - I used the term chassis battery meaning the house batteries. I was just wondering if the RV was plugged into shore power, the disconnect switch within the RV was in the off position, if those two "house" batteries would still charge.

I just may have to grab my volt meter and experiment with those two batteries !

Mine is plugged in but has a timer on it that only activates the power about three hours a day. Fridge is off and open.

We don't camp every weekend, so I unplug our TT between camping trips if it is going to be more than a couple weeks. A few days before camping, plug it back in and turn on the refrig. This has worked well for us for years.

I leave mine unplugged. I don't want to have the Inverter on 24/7 year after year. I do have the battery hooked up to $20 trickle charger outside next to the battery 24/7.
I figure that the Inverter, like any other electrical piece of equipment will eventually break down sooner than later if left running all the time, and it being more difficult to change out and a lot more expensive than a $20 trickle charger to replace someday in the future.
Than their is always the thought that the Inverter could overheat and cause a fire inside the trailer.

I have been rving since the 60's and I can't think of a time I haven't had my RV's plugged into 120V, and I leave my frig turned on also like to store beer in it and if we were to take off on a moment's notice the frig is cold and ready to go

There are 1000's of us that either are or have full-timed in our RV's. We all keep power on 24/7 and I can't remember anybody having a problem due to that issue. I don't think there will be any problems.
