We took our new camper on it's maiden trip over the weekend. The first night was a harvest host stay at a brewery (Brewdog in Columbus - quite good if you are in the area). The battery was fully charged, and the alde system was set to 72 degrees on propane. The system shut down at around 5:30 AM because the battery got too low. Shouldn't the battery be able to handle that system over one night? It did get down to around 37 at night.

We keep our frige set to about 5 on the dial and it uses about 35Amps of electricity. If you ran the 1200W inverter much, it probably drained a good deal of the rest of your battery capacity. Combined with lights, fans, etc. is how I imagine you got drained down.
As @pthomas745 mentioned, almost everyone has that 'bad night' and learns from it. Welcome to the club!

For what it is worth I have added items to my 2023 which many also consider adding...DC-DC converter, 2nd solar controller for portable panels, smart shunt each outlined in bold red. For the DC-DC note the change to the electric brake power.
