Need some help figuring out my next steps, because what I'm doing now isn't working for us. My wife, 3 dogs and I went dry camping in Southeastern Ohio this weekend in the Aliner. Temperatures down in the 20s overnight. Only power use was the heater (thermostat at 55 degrees), 1/2 hour of LED lights, refrigerator (set on propane) and CO monitor. On the first night my battery, a standard Interstate Deep Cycle 12-volt that came with the camper, would no longer power the heater fan by about 4 a.m. It was fully charged about a week before we left, and had been connected to shore power until just a few minutes before we left at 4 that afternoon. So I took my new 500 watt-hour Bluetti, fully charged, and plugged it in as shore power to the normal 30-volt input on the camper (with appropriate converter) thinking that would be the best way to recharge the battery. That night, same thing. I plugged my 100 watt solar panel into the Bluetti to recharge it and got to about 60 percent. Plugged in as shore power again, knowing this was a bit of a lost cause, and the heater cut out by about 2:30 am. We can survive without power. We've camped in tents in even colder weather. But dang it, the camper was supposed to make things more comfortable, and when we've been plugged into shore power, it has. But that's not the way we really like to camp. Should I use the gear I've got differently, replace something, add something to my system?
