How terribly sad - thanks for letting us know. How serious is their situation? I could set up a donation button on the site (separate from here) if they need financial help - I'm sure some of us would chip in.
On a happier note upon looking at the pictures closely I'm not terribly worried about my panels warping or pulling away over time. I noticed that the lower cladding, even where the bed had burned completely through the driver's side does not appear to have pulled away, melted or buckled in any way. If it can take heat concentrations at a level that will melt auto glass, I'm sure the blazing sun won't do much to pop those panels off over time.
One closing note - although burned up, I can see how a "naked" cladding-less Avalanche would look, and I can see how it would work...
