I used the inverter in the bed to charge a portable refrigerator/cooler (Dometic style). This was very inefficient as I’m effectively running a 2kW generator to power a wall brick that covers it back to 12V for the fridge. But, I only had room for the fridge in the bed and there’s no 12V rail back there to tire to. It ran like this for a cross country road trip, 54 hours/2500 miles. Ran fine no issues, though on the first day it smelled like hot electronics under the car. Smell went away eventually, perhaps it was getting broken in…
