We have been camping for years and know about being conservative with battery power. I am wondering if the battery power can be back feeding threw the converter.

I'm not sure what you mean about backing feeding, make sure you don't have your truck connected to the trailer pigtail power. The trailer will drain your truck battery. If you ran your gas furnance it needs power from battery to run the furnance fan.

More info needed. I wonder what all you are trying to run on 12vdc. Many newer fridges have 12vdc compressors and have a high draw. How old is the battery? They don't last forever.

Do you think just a little bit more information might be helpful? You know that we have no idea what trailer/RV you are in, how old is it, what battery do you have? What equipment is in the trailer, is it a 12v only refrigerator, a 120v AC only refrigerator? How are you recharging the battery during the day? Do you start the night with a fully charged battery? Do you have any kind of battery monitor other than the next to worthless 4-lights on the tank level meter? How much are you running the furnace at night? Your question is like, "My car won't start in the morning, what is the problem?" Very Respectfully,  |

WOW Tough crowd lol. I have a 2020 Sonic 190VRB. We used it last year one time dry camping and that's when we discovered the short battery life. It had the factory 12v battery which after the first day I replaced with the biggest battery that would fit in the box. To my suprise the battery had dropped to low the next morning. We made sure to use minimal power and we do have a two way fridge and it was on propane. We used the furnace for about 10 minutes at night just to take the chill off. I am wondering if there's something drawing power that is running in the background that I don't know about.

You'll get use to us hanging around here. Easy to get a DC amp meter, then take a picture of the fuses in the distribution panel. Then pull all the DC fuses in the power distribution panel. Check the draw when each fuse is added back in the panel. One should show up as a high draw. Hopefully, the circuits are noted inside the panel door.

Check to make sure the breakaway emergency brake cable is plugged all the way into the switch.

the biggest battery that would fit in the box. Have you had this biggest battery that would fit in the box tested to see if it is bad? I am unfamiliar with that brand, is the battery an AGM (Absorbed Glass Mat). Lead Acid Battery, Li-ion (lithium-ion) or something else? |

Thanks for all the good ideas. I will check out these ideas and let you know. It is a lead acid battery. I believe the new battery is a 100 amp hours.
