  • Patent number: 5304300
    Abstract: As filter canisters are utilized by recreational vehicles, provision of a single filter canister to the primary water input line exteriorly of the vehicle is provided. The recreational vehicle includes a filter canister mounted exteriorly of the recreational vehicle exteriorly adjacency to the vehicle's fill nozzles, wherein a first fluid supply conduit is directed to the filter canister and in turn mounts a second fluid supply conduit directed into the fill nozzle of the vehicle to effect filtering of the primary water supply of the vehicle. A flange plate is slidably received within a mounting flange for selective positioning and mounting of the canister during use permitting ease of disassembly of the canister relative to the recreational vehicle for ease of transport of the vehicle.
