Many of the pop-ups have a three way fridge, that's the only place I have seen them. My first trailer (a Viking popup) had the three way fridge 12v, 110v, propane.
If the trailer is question has a three way fridge, you should be fine for the 6 hour drive. You should probably turn the fridge on at least 24 hours before loading it with food, then make sure it stays plugged in until you are ready to leave.
