There is also something solar modules can develop called hot spots. This occurs if a solar cell is damaged or broken. All the cells in your module are in series to build up the voltage (individual cells are only good for about 0.5V each) so the current is the same running through of them. If one cell begins to fail it will still be forced to carry the current of all the others so it will get hot. It can get very hot to the point where it burns or discolors the encapsulating materials and, if directly attached, the surface its attached to as well.

There is plenty of flat space on an rPod roof to mount a glass module, or you can leave it unattached and locate it where you want at the campsite. 

There is one type of flexible peel and stick solar module that you can mount to a curved roof surface, if you can find one. These were made by a company called Uni-Solar and are truly flexible, because they are based on a thin film deposition of amorphous (not crystalline) silicon on a stainless steel substrate. Because the thin film silicon is not crystalline, it can't develop fractures. You can even roll them up. The drawback with these modules is they are terribly inefficient, about 1/3 the efficiency of standard crystalline modules. That's why Uni-solar went out of business some years ago, but you can still sometimes find them on ebay etc. If the low efficiency doesn't bother you because you have enough room to mount what you need then you can try one of these, but they're big. They do still heat up the roof becasue of their dark color but they don't generally develop hot spots.
