Has anyone here tried out the removeable Breezer Window (www.breezerwindow.com)? I'm interested in hearing about its quality and security. Basically, I'd like to transport items longer than my short bed (8 to 11 foot windsurf boards and components) that pass through to inside the cab, all within the security of the campershell. Currently the openning of the rear window slider is just way to small for everything to fit. Using a roof rack on the shell is just too inconvenient and I don't trust it because of load security. I'd like to hear your opinion, or ideally if anyone knows of a company that makes large openning sliders. Thanks.
