Water bladders for a 200 series Landcruiser

Mine is a 70l flexitank. No baffles. Fill them without air bubbles and they dont slosh until they are nearly empty. Next to zero taint. The weight is exactly where you want it to be. We use ours only on desert runs etc but wouldn’t be without it.

May be worth having a look at Enmach Industries, they have a range of tanks that may suit your needs

I put one of these behind the middle seat, in front of the cargo barrier.

water storage

Mind you, I now think it's hard to go past the 15l wine cask style containers from coles and wollies.

If not using for drinking and opening big enough then feed in a large number of practice golf balls (white air type) to stop sloshing. May reduce capacity a little bit and small amount of tainting possibly acceptable to many.
Or for a more specialized version.

If you are in two minds about it then leave it at home.
Personally I think most people carry too much water which equals unecessary weight.
Carry enough for personal consumption plus a smaller quantity for utility use that can be topped up in creeks etc on the way.

I am with Boobook with the cask water idea that allows you to reduce storage requirements along the way.

I carry a 100L across the back floor and the portable 120w solar panel sits on top of it when on the move. No baffles as the bladder reduces in size as consumption goes up. Have done a lot of serious off roading without any problems. Had it custom made for $145 delivered to have the filler cap on one end for easy filling. Also have a 45L made for $85 delivered in its own custom made box that sits on top of the rear draws dedicated for cooking and washing when the camper was left behind or just for a quick stop cuppa.
Both had the residue taste at first but after a few soak and rinse all is fine.
Nothing beats not having to worry about water on remote trips.
Jerrys are out of the question for me, I need look after my back.
The 80 and 100 series have totally flat rear floors, meaning no hump in the centre. Not sure about the 200.
I allocate 8-10L per shower which includes washing hair.
I have once traded 10L water for a bottle of good whiskey, only because he was a total A-Hole.
Note: price was in 2012

" and leaving the water in the camper to be used for consumption"

We are of the opposite view. Water in out Tvan or Caravan is used for drinking, washing and showering and water in the car is reserved for drinking.
So when we go for a drive during the day without the trailer we always have good drinking water.

We travel with 20-40L on the car in jerries for drinking and hand washing

Out of curiosity...how are people securing these water bladders in their vehicles?. It's all well and good if nothing goes wrong, but in the event of a crash / roll over i can't say I'd want 50 - 100kgs of water cleaning me up from behind.

Thanks everyone for your comments. They are from a wide spectrum of thinking and all valued considerations. Thanks

I have no rear seats in my 60 series and a 75 ltr bladder fits perfectly across where the rear seat used to be. I used to remove it after each trip but it has been a permanent fitment for the last 10 years or so. I fitted a short piece of 1/2" hose to the filler that is fitted with a tap this is then held high attached by cord to the high seat belt anchor point behind the driver on the door column.
The bladder is inside two (out of use by date) sleeping bags to prevent any abrasion.
There is a false plywood floor covering the whole lot. The water is always cool.
If possible expel all air from the bladder and turn off tap, when filling attach a hose to your potable water supply and turn it on to fill it with water then off, connect to the bladder tap and turn it on and then the water tap and the bladder will fill with water only, no air. When you require water lower the bladder hose end lower than the bladder and bingo nice clean cool water.

I have a 40L rigid poly tank installed between the drawer system and the rear seat with a gravity fed outlet.

I also have a 40L underbody alloy tank with a small pump

In the cabin we carry a 10 or 5L jerry and there is a 2L backpack water bladder in a hiking pack and 1L Nalgene drink bottle

Shower normally costs us around 7-8litres each, a bucket 'bath' half that.

Water is our only beverage after tea and coffee.
