I'm curious about the roofing material used. I have an '06 Greyhawk and it has the TPO roof, no problems so far, and Jayco says they have switched to that material instead of the EPDM but I've heard from others on another forum that they are using both. Did the inspector say which is which, and also the warranty from Jayco (at least on mine) only warranties the roofing material to the original owner. You bought yours used, as I did also so I'm surprised you got a replacement. Jerry
Sorry for the typo on the header, I can't seem to edit it out.
