Battery disconnect - can I still use my heat?

As long as they are fully charged, you can disconnect them and leave them that way if you want. When it's cold, the self discharge rate is very low. The converter will run your furnace.

I guess I don't understand why you'd plug in and disconnect batteries, you will kill them if you don't maintain their charge over a long period.

I get that it seems counterintuitive, I'm not planning on spending much time in there while it's winterized but for the odd occasion that I want to, I just want to make sure that the heat will still work if I disconnected the batteries.

Most battery advice tells you to disconnect the batteries when not in use for an extended time, so that's where I am thinking that I need to disconnect them.
A guy at the battery shop was saying that even a small draw on the battery will create a situation where it's charging all the time and that isn't best for the battery. I see plenty who leave them connected and have no issue either. :)

Let me add some nuance here, I agree with those that are for disconnecting your batteries but for a bit different reason:

While it is true that your converter SHOULD keep your batteries properly charrged this depends entirely on the quality and operating condition of your converter which I am sure is not known to you.

Therefore the most sensible thing to do is to disconnect.

I disconnect mine if I am parked for more than a week and always when stored which for me is rare since I full time.

HA ha - a little bit of both ;)

Man cave or potential dog house?

Thanks for the input! My rig is only 2 years old. Sounds like half are saying to just leave the batteries connected and the others say to disconnect. It charges it to 13.1 V, and I do regularly check the water levels. So far so good. I want to install a cut off switch, that'd be nice and easy and then I will disconnect them when not in use.
Most importantly, I appreciate knowing I can just leave the converter on so I can use the heat if I want to use it as a man cave this winter.
Thanks!

Mine stays plugged in any time it is in storage. And since we always have FHU sites, the only time it is not plugged in is when we are on the highway. 11 years and I have replaced the batteries one time. I do check the water regularly.

Your batteries would be better off if you disconnected them instead of leaving them on a float charge.
The converter will provide enough to run the heater if you need to.

but remember to service the batteries couple times a year check water ,etc.
