The only thing that concerns me is the fact that the tray has been replaced 4 times. It suggests that the installation and support is poor. I have a similar problem with a swift but have been lucky to find a replacement even though the van is 18 yrs old. It will be having much more support put down before the new tray goes down. I have heard good reports about speedboat but wonder how they overcome inbuilt cr@p workmanship ?
