Our 2006 Alpine Apex has a Vagabond RO water system that takes HARD 460 PPM TDS (total disolved solids) Palm Springs water down to about 15, darn near distilled. It also handles 900+ TDS water in Arizona. No need to wipe down the shower to avoid water spots. We use RO water from the fresh water tank exclusively and an automated system fills it when a preset low level is reached. I will never have another coach without it!

The water in AZ where we spend the winter is 50 grains per gallon and my neighbor was haveing to recharge his Waterstick every 4 days. The Mark 8000 will last about 14 days there.
Can this also be used for exterior coach washing to help prevent water spotting?

I've run vinegar through the lines for years, it works great. On occasion I will still run some blach instead. We use vinegar to clean many things. One shotglass of vinegar to a gallon of water for hard surface flooring, and using vinegar instead of fabric softener keeps the clothes soft and you don't smell like a walking fabric softener sheet.

Bullheaded- I have whole-house RO in my coach, and use it to wash windshield when we stop, as well as coach exterior (funny how that's necessary where they rain sprinkler water on your coach every night, but not funny ha-ha). Works great. We even fill from a hose in Baja when traveling there.

I have pre-filters (one depth media sediment, and one carbon-block), prior to the RO membrane. As mentioned above, filters (outside of some pretty esoteric ion-exchange stuff that will have limited life span on the quantity we are talking) don't remove dissolved solids, i.e. hardness and other salts from the water passing thru. We run a 0.5 micron sediment filter in Mexico which is good for most bacteria & cysts, and then the RO. Even salty tasting Southern California water comes out tasting fresh & clean, not to mention the easy clean up. Whole house RO isn't cheap, but I decided it was one place I wanted an upgrade. The improvement surprised me. When I traded my 06 coach w/my first RO system in it for the 08 coach, I bought the whole system again. Best thing we've done for the coach, both times. My wife loves it.

Yes it can.
The treated water hardness is about 2 grains per gallon after regeneration and until it gets up over 10 or (maybe 15) so grains per gallon you see few if any water spots .
