12V power port in tent endsNo accessories etc.....just the 12V Power Port
Per Manual
12-VOLT DC OUTLET (IF SO EQUIPPED) There may be a 12-volt DC outlet (not applicable on all models) in your RV. When the 12-volt DC outlet is used as a power source for an electric appliance, make sure that the appliance operates on 12-volt DC power and that it consumes less than 60 watts (5 amps) of 12-volt power. To prevent short circuits do not allow metallic foreign matter to get into the 12-volt DC outlet.So IF you can find a 12V DC appliance that can be plugged into that power port and is 60W or less looks like yo can use it.
