Any body use a portable water softener for your RV?

Initially I thought this post must be a yuppie wind up - but then thought, probably yes in the USA, sadly true, and no shortage of brands and models.

Didn't find any for sale in Australia in a quick search, not surprising, and didn't expect too. No doubt some Australian RV manufacturer will offer a water softener as a sales gimmick.

I expect most would do what we do, that if the local water is not the best, they buy 5L/10L of water for drinking. Same as when travelling into areas we know the water is not the best or not treated for drinking throw in a 10L or even perhaps two.

We are buying 10L containers of water for drinking at home at the moment because of the drought and fires. The water in the water tanks is tasting so smokey, and where we can fill with town water, the town water supply is so low in the dam the water quality taste is not the best. First time ever bought drinking water for home use.
Water softeners are not a common item in homes in Australia. Australian town treated water supplies are generally of a high standard. Not many locations in Australia town treated water has so much calcium and iron etc. that people use water softeners. Reverse osmosis units are more popular for domestic use and superior to water softeners. In towns where the town treated water is higher than is desirable in dissolved minerals, they would generally install rain water tanks, and have an extra tap in the kitchen and/or bathroom for drinking water.

A water softener is referred to as a unit, consumed for the purpose of softening the water via eliminating the minerals that cause it to be hard.

I assume the OP meant to say potable water not portable water.
