Pulled mine out and put in in the garage...added a large unit to the house and had them account for the truck and it has been much easier.....either way..on the truck or in the garage....I would not be with out one....
I use soft water when I fill up at the house and descale every 500 hours. Most of the water around here isn’t too hard except for some of the small towns. From what I have seen most guys that have water softeners on the truck don’t keep them charged.
