For showering I bring a Do-Dad that I think was invented by an Aussie that attaches to a drink bottle of any size with mouth sizes up 50mm, I usually use a dedicated 1 litre bottle and can get 15 minutes out of it. It has a valve that you just lightliy pull out and a few minute holes in the head. It was expensive at $25 but very useful. I do not need to stealth camp here as not really required to do, but if I am within 15 km of a town or city, you have to do it, as camping inside that zone usually incurs the wrath of a ranger. I camp 995 of the time as prefer not to pay. Will use a caravan park when need a decent shower or laundry or power to charge, although have a solar panel and battery 35000ma.
