I'm not familiar with that particular number. I assume you already have a housing installed and that is the cartridge number.
Most RV manufacturers install a housing that will accept just about any standard 10" cartridge. Most RVers use a combination taste-odor-particulate cartridge.
The cartridge I use is a Hydro Life C2063
. It is a taste-odor-particulate cartridge that also removes a lot of other stuff like heavy metals and volatile organic compounds. It is more expensive than most, but it also contains a bacteria fighter that will prevent bacteria from growing inside the filter. IMO this is important for weekenders who only use their RV periodically because the filter could have water just sitting in it for several weeks at a time between uses.
