Thanks Pete , I forgot of the previous edit on water system .
@ Damienperu , the pump has a 12 L / min flow, sufficient for washing things and making a shower.
Not for washing the car, but was not intended for that.
Bigger pump flow are aviAble ,but will result in a wast of water.
No filter system , because if you use tap water ,generally there is no need .
If you use river -lake water the system sucks the water and I use a simple filter at the beginning of the hose.
For sanitizing water , I add some drops of Micropur, that is a very efficient silver ion liquid.
Leaks , this was an issue at the beginning, after some trips I fixed all joints .
I found that the best joints were air pressure tubes in Rislan , with quick joint system.
Don't use the very flexible Rislan tubes , they are flexible ,but due to this feature they tend to generate some leaks under pressure.
Depending where you go ,and aviablity of water you could eventually simplify the system in avoiding the 3 valve ,pump -suck .
If only pump, so you save the 3 valve and many many joints . 9 joints.
General rule ,more joints more leak possibilities.
As soon as I return home I will make more pictures of details of the water system.
I looks that my water systems gets more interest then the pop up roof .
