While walking around a local campground yesterday, I came across a fifth wheel with an awning (patio type, not slide topper) on their back side kitchen slide. It was not a GD product but the slide was configured just like then one on my 303. The awning was clearly installed to shade the refrigerator. The owner wasn't at their campsite so I could not inquire about it. Has anyone done this? If so, how effective is it? My current and previous experience indicates that RV refrigerators struggle to maintain steady temps when the sun is beating on the wall behind them.
