Bought a 2008 Fun Deck 2000. Layers of unnecessary weather stripping around head door opening. Asked to have it removed by seller. Upon delivery still a mess of weather stripping and silicon. I discovered after removing mess, that it was covering up a separation between head module and the main body. Warped all the way around with 1/2 in gaps. 2008 was the first year I believe. Design issue? Any factory support in this area?
