Now it's working, so I guess when not wanting to run the fridge I could either turn off the inverter or the battery disconnect now. Just wondering if it's OK to leave on.
It makes sense it would be, otherwise if power went out, there's no backup for the fridge like we had with propane before.

We have the same RV, came with 2 12V batteries and found it just was not enough, even though there is enough juice for the Refer, in longer travel days there was barely enough for the jacks and slides. I upgraded to 4 6V batteries (total cost was $600) I also installed a automatic watering system for $80. So they are basically no maintenance batteries. Since AGM batteries have a shorter life and twice the cost this was the best solution short of spending $2k for lithium.
Also note I added a switch to my negative cable to the battery that way I can shut the batteries down 100% otherwise there is always a small battery drain when unplugged.
Here is what I did in my 3791RD
I installed my 4 Trojans removing the two 12v. As you can see the battery box barely fits but is doable. Even if you only buy two 12V you should still buy the 4 battery box so you can easily upgrade. You can just build a filler to take up the extra space. This is also enough for an over night boondock if needed...
As mentioned above I purchased 4 Trojan T105 Plus 225 AH $125 Ea no tax and no core required ($500 total )

the Battery Box was purchased from All Battery Sales and Service $80

I Just ordered the Watering system for $79 so they will for the most part be Maintenance free as I will gravity feed the system.
