I just went to a local Webasto installer and he quoted $1200 out the door for installation of a Hollandia 730. He said that I'd have to either remove or re mount my roof basket back a bit to clear the tilt function.
So I was looking through your gallery and found this pic. Is the clearance issue related to your basket or your fairing? It sure looks like you'd have a hard time hitting the basket, but I could definitely see where your fairing would be in the way.
