Hey Renee , welcome to the madness!
I used FRP on my TD & am very happy with it. I have been parking it outside all the time & have yet to have any UV issues as has been dicussed on this forum. It washes up very nicely & no stains,( its parked under a cherry tree!) I found the panels at HD & Lowes. About 28 to 30. bucks each.
Check out my album for pics. Cause we all love da pics! I'm sure you'll hear this again soon! Good luck with your build!
