Thanks Frank. I would rather pay a premium on transport rather than removing the arch. How about canvas and the aluminum supports? is this difficult? I wouldn't think so, but I have no experience with a 450. If I do remove canvas then what do I cover the gauges with? I'm moving the boat in November (if all goes accordingly) so there is the potential for weather. I have a concern, perhaps unwarranted, about theft of dash displays. Seems like an easy target for thieves? Transport company is insured but if parked overnight at a truck stop or motel..? I would rather not meet the transport at the marina to see the Garmin ripped off, etc.
