Regarding the cover… See the slots on the knobs on the four corners? Stick a coin into the slots and turn them 90° and the covers come right off.

The DC mode is to keep the fridge cool during travel. You really shouldn’t use propane since the vents are covered. But it is a ridiculous draw and unfortunately most vehicles 12V+ charge circuit on the Bargman 7-pin can’t keep up. Mine will run a 2-3 hours while towing and then the battery is completely flat. I’m installing a dorm fridge and inverter. Cooling while towing is a big part of the reasons why.
