I know I'm one of many, but considering I'm no electrical genius I'm proud of this mod: Baffle and 120mm fan: On/off switch to the right of the galley: The 120mm fan was more expensive than I was expecting for some reason ($15 @ Radio Shack), but with the switch and fan I was still into it for less than $20. I had the materials for the baffle laying around the garage already. We leave again tomorrow for Eastern Washington (100-degree temps forcasted) and it was 90 in my driveway today. I fired the fridge up without the fan at first and it came down from 70 to the high 40's in a couple of hours (baffle only at this point). I turned on the fan at about 5:00 and by 8:00 it was down to 35 inside! The outside ambient temperature was still 88 at this point, there was still a lot of sun exposure to the trailer, and the interior wasn't vented at all (completely sealed up and was HOT inside)! My multimeter showed the battery had 12.41 volts before I turned the fan on and after about 3 hours it was only down to 12.35 or so. I was expecting it to have more of a drain on the battery but at this rate I could leave the fan on for an entire 4-5 day trip and use lights normally at night and probably not get below 8 or 9 volts. This thing ought to rock!
