Most New England state parks wont allow generator runs except during set hours and not at night,however Mass state CGs allow for medical devices however you could be asked to move if neighbors complain. Myself I have a 12v adapter for my CPAP and run it off of house batteries or https://www.amazon.com/STANLEY-J5C09...v+jump+starter ,that I recharge off of car or when I can run generator. DW would rather hear me snore than have to listen to generator all night:D:roflblack::roflblack:

Wow, thanks to everyone for your responses! I've learned a lot from all of you. We obviously didn't get a very good orientation to the unit when we bought it especially around the use of the batteries vs. generation etc. I had no idea the batteries would run the furnace blower and other things besides the lights.

Prior to our last trip we did buy a small ceramic heater to heat up the unit and a electric blanket to warm up the bed before going to bed. We are primarily traveling for dog sports which means many of our nights camping will be boondocking. I will continue to research the forum to learn more about batteries, and the electric systems.

You all are great!!!!

Here is an often-shared article on 12v systems. Maybe it’ll help:

Basically, your battery will run the furnace blower, water heater (maybe), lights, and possibly the fridge (depending on a few factors- it’s either all 120v or propane+electric). There are 12v TVs - they’re less common but sometimes come in motorhomes.

Otherwise, if it’s a regular household outlet, it’s 120v. You either need shore power, generator, or an inverter.

Just remember- your battery power is typically fairly limited. You can’t go hog wild without running it down at night. Run it down too far and you can damage the battery(ies).
