Does anyone know where I might purchase a new seal for the battery compartment on my Fleetwood Colchester 1500-2eb 1996. I have tried Fleetwood direct for other items but have yet to get a reply from there sales dept for anything asked for. very dissapointing!!. having just noticed it missing I can't even take it as a sample should I locate a company/shop that keep a cross section of different seals. Any help would be appreciated.
