Water storage

Unless you are going to a very remote & waterless area I dont see any reason to lump
120Kg plus weight of tank around. We carry 2 by 20l plastic drums..one of good old rain water for our tea & drinking, & the other for washing/showering etc. We refill at
parks,servos..wherever as required, & have never run short. If you intend doing the
CSR or Simpson etc, you would ,of course carry extra as availability & safety dictate.
If you think you may need more than this, carry empty containers & fill as necessary.
To cart more only uses fuel & space...IMHO....cheers...oldbaz.

2 x under-tray water tanks that also serve as a mud flap might be the way to go. I have 2 x 50ltr.

They are the ones in front of the hheels, but you can get them to go behind as well

Litlbalt - you are on the right track with your thoughts of 2 isolated tanks.

About 20 years ago I made the mistake of having a 100L stainless tank custom made for our Bravo (at the time) prior to a central Australian trip - Tanami and Simpson desert.

The first problem that we encountered was when we elected to NOT top up the tank at Purnie Bore. This would have meant we were adding about 30 litres of bore water on top of 70 litres of nice fresh drinking water we had been carrying. So rather than make a 'brew' we elected not to add the extra water.

Futher into our trip, one of our traveling companions vehicles broke a rear main leaf. So the rest of us helped by lightening his load as much as we could.
We took as much fresh water from him so as to fill our 100 L tank.

The second problem came about I feel because I had failed to leave any 'ullage' (spare room) in the tank and the sloshing caused the tank to split on one of the welded seams. Fortunately it wasn't a bottom seam - but we lost a considerable amount of precious water.

On our return home I had the tank cut in half and ended up with 2 X 50 litre tanks - completely isolated and it then gave us the option of transferring good drinking water all into one tank if we needed to top up from bore, creek or dam.

2 tanks - definitely the way to go - and not all the eggs in one basket.

Hi Litlbalt

Unless going to somewhere dry and remote for some time, you will be able to obtain water regularly. Prior to our present caravan, we travelled with a couple of jerry cans; one for drinking water and one for general water. It is also easier to take a jerry can or two to a water source and fill than to fill large tray mounted water tanks. Also if you are in areas where water is short, most places will let you fill a jerry can, but may baulk at you filling a large tank. Fees for water apply in some places.

We opt for using less water when in remote dry areas. It might be harder with children, but we can manage on very few litres water per day (plus drinking water). This allows for a full wash every night.Water economy

As the article heading linked to your post says, an alternate tank for water of poorer quality is needed, aside from an leakage issues.

Thanks for all your info. We have decided to have a smaller tank and then have a couple of jerry's one full and another empty to fill if we feel we need more.
