Too Much Sun!

I'd venture to guess 8 - 10 years is about the upper lifespan of awning material. Depends on whether you have any covered storage during your owwnership of the rig. Aerospace 303 will help if you start using it from day one ... once frayed it will not. There is an outfit in Trailer Life magazine that sells a PVC like split tube advertised to extend the life of any awning. Replacing the awning fabric when it comes to it isn't all that hard nor that expensive. Two people and two ladders is a must.
