NEVER let the batteries go below 50% charge.

Didn't you upgrade your converter? My WFCO would take about 8 hours to recharge from 50%. That's why I upgraded to progressive dynamics.

Let the gen run the whole TT and not just charge the battery. The converter will do it's job charging and you can use other appliances while the gen runs. Otherwise, you are just wasting gas and electricity as the Gen will probably have a lesser charge rate than your converter.
I would give serious thought to a second battery if you only have one.

Nope.
Original WFCO converter.
It's been working like a charm for 10 years now, Knock on Wood.

If you have two 12v batteries, do you parallel them together or use a switch to change over to second battery when one is getting good low,

I always use them together.
That way they share the load.

You can install a marine battery disconnect switch that allows you to use both or each separately.

Hi Bikendan,

Curious - how do you ensure you don't go below 50% charge? Meaning do you have something hooked up to your dual 12 volt batteries to be able to see the charge?

Multimeter cause mine was free and installing a good battery monitor, like Trimetric cost more.

These are modest demands and it should not take much. As noted already power the 110V portion of the RV from the generator and let your RV converter do the battery charging.

It is entirely correct that we cannot tell you what it will take in time. This will even vary for you from one trip to the next. This is why having measurement devices is key. A prior poster gave you an example of a simple plug in voltage measurement device and a battery charge level table. Start with something like this and monitor where things go. If the voltage does not drop much you can run the generator less or vice versa.

The next step up in monitoring is to add a meter which measures both voltage and current. This will enable you to have an idea how much power your devices use and you can use that knowledge to build a power budget or manage use patterns. There are much more expensive and capable versions out there but I put one of these in my Rockwood: bayite DC 6.5-100V 0-100A LCD Display Digital Current Voltage. This meter also tracks power usage over time. The biggest limitation is it only tracks current out and not in so you cannot measure charging power.

Adding heater use to your scenario will be the next step up in consumption as the blower will pull 4-5 amps whenever it is on.

In my TT during summer we survived a few days of boondocking just great with a single basic group 24 12V battery and a 100W solar panel. Refridgerator, water pump, LED lights, and the background draws. I think in winter I would need to add a second battery and jump to 200W of solar to handle the addition of the heater.
