Chances are you won't be able to raise it with the existing caps even though thier new. The trend is you oreder caps according to how high you want to raise it. That gives you about a two inch overlap between the caps and the framing for riveting. Your at an ideal time to RE-raise it though since the coach is in the state that you say it is. BUT...It would mean purchasing new caps.
I believe you can raise an eagle up to 14 inches max with a special order from R&M Fiberglass. The sight you might have saw the roof raise done could have been at mine. I had failrly detailed pics of the MC9 I did at:http://community.webshots.com/user/greggpaciga
