I installed a water softener in our Itasca Horizon two years ago and it has been one of my better mods. I thought others might like to see this installation. The water softener was purchased at Camping World for $300. I used an outdoor electrical outlet to make a door for the water hoses. I installed the softener in the storage bay next to the water compartment. Once the slide is extended, I run the water lines out the aft end of the slide. I use brass quick connections on the water hoses.
I find I can use the softener for about two weeks before it needs to be regenerated. It takes 6-7 cups of rock salt and about 15 minutes to perform the regeneration. We are finding that the softened water is much better for the Splendide washer and the coach water lines. There is a noticeable difference in the clothing washed in softened water as well. And, you can feel the difference in the shower. Here are several photos:
