Brian, now that's nice.† You mention mirrors - is there any way to mount the new style mirrors from the top (I think Setras, maybe Van Hools) have them)?† I don't know about appearance, but if you have a blind spot issue with the current mirrors, it may be an option.
There is a minor blind spot problem with the current mirrors, but they main issue is they just plain suck compared to most RV/Bus mirrors. JD at C&J Bus Repair commented on the bad mirrors the first day he used them when he had to back it into a parking spot. They are very narrow and don't show very much of the road.
I did buy a set of mirrors for $300 from RontheBusNut that are like what the newer Setras have. I just got them Saturday and haven't had much time to figure out how to mount them.
