It sometimes seems the roof is the most vulnerable part of an RV. It can leak, be damaged by the sun or hail, and is probably the most significant heat sink on the rig.
Since my vintage A/C was deemed 'sufficient' by Camping World, I'm looking at other was to draw or prevent heat from my good ol' Argosy 28 MH. Am not sure, but I think aluminum walled RVs make excellent large format solar ovens. Has anyone here installed a cover over their roof that can travel with the RV? Something like this: http://www.shaderv.com/
Seems like an awning that extends over the roof of the RV would reduce heat, sun damage and perhaps reduce leaks? Seems like one could somehow roll up a tarp from the Home Depot around one or more lengths of 4" PVC drain pipe and rig some kind of frame work to keep it off the roof yet still attached to the RV in high wind. It'd have to be easy to roll out and roll up for transport.
Any ideas - or better yet actual implementations? This question doesn't strictly pertain to Argosy Motorhomes, I just spend most of my time in this particular forum.
