What year is the trailer? Private seller or dealer?
Ask the seller to turn on the fridge at least several hours prior to your arrival. Bring a thermometer to check the temperature. Most fridge can take several hours to even a day to get cold. The freezer will get cold first then the fridge.
When running the fridge on propane the battery should be on.
There's been several members that ran into serious problems after plugging their trailer directly into the house power without using an adapter. Please inquire about this from members with more experience and knowledge.
