About ten years back I build a 34 metre ocean going yacht were lode and balance is of upmost importance and all I used was coke bottles. Each bottle becomes a mini tank so no sway or slosh at all. We found drilling holes a better way of doing it.We removed the lid and drilled 8 holes on the sides and 4 at the bottom. I have done the same in my van with an upright tank and am never aware of the water even at speed.The baffle in the tanks is hopeless as they allow to much movement. If I was an insurance company I would be more strict on this than steel frames.As closer the  baffles and smaller complemented will make the van more stable.Up right tanks in my mind achieve this balance better.

Thanks for replys.

I think am heading towards the layflat tank due to the van being a bit more stable when driving. I don't really mind parking on a kerb to get the last of the water but i don't think i would use it all in a day anyway. I am still deciding but think il end up going for a layflat.. am like an old woman   trying to make a decision lol

depends, could make it out of 2 smaller tanks, like some 500lt systems are made with 2 250lt upright tanks plumbed together,

Ive got 2 upright 250 tanks linked secured in a frame.
Very stable and doesnt take up too much room.

i was thinking about making a 560litre tank out of two 280litre upright tanks,

do you find far less sloshing around with the 2 tanks?

I dont know what its like with a single tank, ive only ever used 1 of the 250 tanks on its own the upgraded by adding another 5 years ago.
I must say though that having 500 ltrs in the back of my 2.0 HDI Dispatch it doesnt hardly notice its there .

The best choice is a fully baffled flat tank. This maintains a low centre of gravity which will help with road-holding, MPG, tyre & suspension wear etc. The baffling needs to be of the multi-pocket type (as mentioned above) as generally the structural baffles are not enough. One of the best ways is to get drainage pipe of any type and cut lengths just short enough to be dropped into the lid of the tank and to stand upright in the tank. Simply slide the first one in and fit another - carry on doing so until the tank is full.

A large upright tank is simply not as safe and will adversely affect your vehicles handing and performance. It also will perform far worse in a crash situation. When carrying out crash testing of our own tanks we found that the lower the tank the less effort it took to hold it in place - the result is that we now have the lowest profile of any crash-tested tank and restraint system.

The other advantage is that there is a good amount of room above the tank in most situations to fit other goods if you need to transport stuff in your van at the weekend.

I don't know if anyone has seen these but there is a product called baffle balls not sure on the make etc but they looked awsome and tell you exactly how many you need to stop movement per litre so just order the rite amoant for your tank and your sorted

thanks for the replies.

Think i will end up going for a 350 layflat tank just make sure i close tap when driving between jobs lol.

I cant put too small tanks together as i am getting it installed properly.

They won't fit through the top of a wydale baffled tank.

Grippamax do a 400l  lay flat tank which is crash tested.

My personal preference would be a cube shaped tank but this does need to be custom made.
