With a fridge in the trailer I wanted a solar panel, mainly to extend the amount of time between charges. I don't have enough room for the 60-80 watt panels needed to make the trailer completely self sufficient, but the 20 watt panel should help, and pretty much run the fridge as long as the panel has sun.
There is only one spot where I could install a panel, and that was next to the tent on the top of the trailer. I had always wanted to bedline that upper diamond plate section (mainly for looks), but I didn't want the top of the trailer that gets direct sunlight to be black. The diamond plate reflects sunlight and heat a lot better than flat black, and when the fridge is directly below that panel it makes a difference in how hard the compressor has to work. But the new solar panel will cover most of that panel and there will be an air gap below it, so I hit it with some Dupli-Color bed liner. I also added a crossbar to protect the panel from getting bumped, or rocks from the 4Runner tires hitting it.
