Cool rig! Mind sharing any pix of the flexitank and how you installed it/what it looks like? Thanks!
Wow, Dave, thanks for sharing all of this detail! Have you considered or evaluated using it for drinking water? I have Jerry cans attached to my rear bumper setup and I'm contemplating how I can do a built in option. I'm seeing some stainless options where you can mount in the spare spot under the rig too.Hi, this is the flexitank.

It has a marked capacity of 25 litres, but IIRC it is nearer 27....ish? Fitment pictures in a 'safe' place, if I find them I will post them up.
The tank goes in the right hand rear quarter, if you remove the plastic panel complete with the little box the bag goes right in, the rear box part of the compartment is removed from the trim. I lined the cavity with a foam insulation material. The bag is suspended from the three nuts you can see, for whatever reason one of the three holes did not line up on the 80, I am unsure if this was an issue with my particular car or the bag manufacture, but easy to rectify. After making holes for the fill and supply pipe, the plastic trim clips back in place. The lid of the little storage box goes back and if removed it just shows the side of the bag, so in effect a dummy.
Now that was the first attempt, after a couple of months the second was more successful. I will explain.
The main problem is the weight of the water, it causes the bag to bellow out at the side, this pushes on the plastic trim and causes it to bulge outwards. This also makes the fill pipe pull down on the trim putting a crease near the filler neck, this causes it to make filling a slow process. Another issue is my passengers kept mentioning they could hear water sloshing around, I could not hear it at the front unless all windows were up and it was quiet in the car, I had never noticed it prior to someone mentioning hearing water.
So the bag was removed while a batten was measured to fit across the opening, my carpenter friend (Pete) used doweling as being round it will not dig into the bag material, which incidentally is very strong anyway, but just being careful, I also had some similar cuts of doweling and had then fitted around the curve at the wheel arch.
Next a piece of IIRC 8mm ply was cut and shaped to cover the straight area of the plastic panel, this was then screwed temporarily in place. The plastic trim then curves out towards the front and rear of the body, easy for the plastic but not the wood. So I cut the curved pieces off the plastic trim and fixed them to the wood panel, a sheet of material glued over the top covered it all nice and neat. The wood along with the material covering has made the movement of water pretty much inaudible to passengers, I have not noticed it either but, having said that I never noticed it before.
The pipe at the bottom of the bag gravity feeds into a 12v water pump with a pressure drop switch, this can be connected to a pipe for use, this is mainly dog water and hand washing at stops on the trail, there is a connector so it can be quickly connected to a shower head, the water is quite warm at the end of the day so nice to get rid of the daily dust. The heat is radiated from the sun on the dark coloured paint through to the bag and some (guessing here) rising up from the exhaust?
This was finished around September last year, no signs of bulging at all and has seen plenty of use. Use common sense with water cleanliness.

Dave
interesting. pls keep us informed about the solar trickle charging, Im on the verge of getting involved myself.
and, today I am also working on a friend's TD5, its broken an exhaust stud, so getting heli-coiled. wish us luck![]()
