I have the wired fin fan. We are in the same situation. I typically pick it up a day or so before the trip. When I pick it up I turn the gas on, turn the fridge on gas and clip the fan to the fridge. I also turn the vent fan on as soon as I get to the trailer (Maxx air vent is a must IMHO). When I get it home I plug it in and change the fridge to auto. Next I put a gallon jug of frozen water in the freezer we keep in our chest freezer in the utility room. That seems to help cool it faster. My father in law is an HVAC tech and says the more cold stuff you can put in there the faster and easier it will cool. Also typically put a bunch of frozen icee pops in there, donít care if those melt a little. After it has cooled (about 3 hours) I put the sodas in there and take the frozen water jug out. I read that putting frozen items I there (Icee pops) help cool it down faster. If there is no chance of rain I open the windows and allow the trailer to cool down before I go to bed and close it up. In south Texas we have camped in 100 F weather with only a little shade and have no problem keeping ice-cream and Icee pops frozen the entire trip.
