I own an 04 SY. You will greatly benefit joining a Yahoo Group:https://groups.yahoo.com/neo/groups/...sations/topics
This is the largest group of owners and you will find answers to all your questions and get assistance. Also they have documentation.
As to your blisters it is also on the site. If left unattended you will get more and eventually have mold behind your siding. They are only cosmetic when they have not broken after that the water intrusion will get worse. Fixing them is also well defined on Crane composites website under filon repairs.
Cost is between some marine epoxy, a dremel moto tool, and polar white paint to a $30,000.00 complete siding replacement and paint at a professional shop.
By now you have lifted up the dash did you also notice there is a hinged lever to hold the dash open.
Good Luck with your toy
