We had an 'Everpure' filter.. installed in 1999 when Mjolnir was built. As it would have it, there are no filters 'available' or manufactured for our filter head assembly... or this post may never have happened.
Here is a link... it is a 3M filter head at Lowes:

The filter removes most of the stuff we are concerned about..
- Reduces 99% lead reduction and microbial cysts for healthy living filtration
- Lead and microbial cysts may or may not be in your water
- Provides enhanced reduction of chlorine taste and odor, sand, sediment, rust, and soil
- Installs in less than 30 minutes
Maintains high water flow at 1.5 gallons per minute and requires no dedicated fa- ucet head
- 1,500 gallons capacity with a 6-month filter life
This is the filter cartridge... # 790058 Model # 3US-MAX-F01H
Obviously there will be plumbing changes.. Time will tell how it holds up to RV life...
Since there is no 'lock' to secure the cartridge, I used a long velcro strap, looped from top to bottom and back up. It fits into some grooves on the bottom of the filter element. Rotation should be minimal.. again, the trip to International will show any issues.
I also carry a few PEX components which I used for the install. It helps to be near a plumbing store for the install... because while most fittings are there for a new install, your situation may be different where you want to install, etc.
There are some 'kit's you can buy for 'sink water dispenser'.. as well as small Osmosis systems.. if you have need for the best water filtration...
Be well
