Water Water everwhere---

[Pedro_The_Swift]

Try this quick quiz,,,
you have around 22 feet of caravan to play with,,
You must have
A. a fresh water tank
B. a grey water tank
C. a black water tank

For the sake of argument we'll be using the tank below, even though 80 litres of water is not enough--

The question is-
how do you arrange the tanks?

D2 :--< B C A
??

think about weight transfer over time--
(also about placement either side of twin axles--)

I understand there is only 9 permutations,,
and I am fairly sure the correct answer depends on the individual van--
but say we disregard axles--

which way?
and why?

As fresh water is used, grey and black increase so I would put the fresh in the middle where its range of levels will have no effect on front or rear weight. As grey volume should increase faster than black I would put the grey towards the front because heavier at the front is less of a problem than heavier at the rear.

Excellent!
obviously the grey tank is only used as required ;)
In reality I think the black and grey will only be half that size, a 40l black water tank would still take us two weeks to fill, if we never left the van![biggrin]
and 40l grey, would not take long, but we dont tend to stay long in places where grey water is a problem,
and we still need to increase water capacity,

so now we can have a second water tank, D, also 80L

--< A B/C D ?

and use D first?

Mine has 2 fresh water tanks, 1 in front and 1 behind the axles but currently they're paralleled so empty at about the same rate and therefore don't change the balance. However I want to isolate them but haven't given much thought to how not to affect the balance without continuously swapping between the 2. However as 1 is just forward of the front axle and the other just behind the rear axle, totally emptying 1 with the other full would induce an inbalance of probably only 1/3 the weight of a tank of water at the front or rear of the van, which I consider would be quite insignificant.

I have 2x60l tanks back & front of the axle & around 100l grey in 2 linked tanks right at the back. The order of tanks usage is usually left front first then left back followed by the right tanks in the same order. I do my best not to travel too far with full grey water tanks but have never experienced any instability with them full.

so Milton, yours are split east-west down the axis of the van?
interesting,,,
