I've been considering getting a van mount system for a while. I currently use a static ro/di set-up to fill jerrycans which then supply my shurflo backpack. New work means that I am now struggling to carry sufficient water for a day's work and so thoughts have turned to a 600-650 litre van mount. Whilst I would love to get a Gardiners Zero system, I can't justify £4k for it when I already have a number of the necessary components at home. My plan is to fit a 650 flat tank in to a Transit-size van, then add my existing pre-filter, 4040 ro (with new membrane) and 7 litre di vessel, and use a Shurflo/Varistream combo powered by a leisure battery (which I also own already). I also hope to run a 500w inverter off this, which I will use to power a 260 w caravan radiator, particularly in the winter. As I also like to go camping/mountain biking/surfing, I then intend to install a false floor over the whole lot (with removable panels to allow access to filters, tank lid etc) and a front panel to neaten it all up, which will allow me to use the rest of the space for storage/sleeping if I go away. I figure with a bit of planning, paint and ducting I can make this look very neat indeed. Now my questions:
1. What type of hose would you use to link all these bits together? And where connections are needed, what type of connectors would you suggest?
2. What type of wire/cable would you use to link the pump/battery/varistream? I will get the battery wired in with a split charging thingy.
3. The tank will need to be strapped down. I realise that I can't use the load loops in the van, so I am assuming (and you know what they say about that...) that I would need to cut holes in the floor and run a goodly number of 5 tonne ratchet straps round the chassis. Yes or no? How would you stop the straps fraying on the edges of the cut hole? Could you line the hole with a section of hose that had been sliced along it's length?
Any thoughts gratefully appreciated, and if you think I've missed anything please shout!
