Hi,
The panel in the link is a Uni-Solar. It is true it requires more room but it does have a 20 year warranty on output. There is also no glass to break. Heat dissipation is superior in non glass panels, as they have less mass.

I'm not a fan of thin film panels. They require more surface area to generate the same amount of power. They also degrade faster than standard panels. Probably not an issue for an RV though.
I also agree about air flow. Thin film panels are subject to the same heat issues as any other. The air gap does make a difference.
