Dave, I believe you would be happy with the Friendship G8. It is a great coach and well made. I am not sure about the Sunroof since I don't have one, but some like them and some don't. Gulfstream use to have another coach called the Atrium, but they had some water leak problems. My understanding is that Gulfstream corrected that problem with an overlay on the seals, so the Friendship should be OK. I like the heating system that you mentioned. Good luck on your bid.
