Hi all. New to this site and it looks great. I have a 2010 D22 and want to fit an underbody water tank - has anyone done this? If so what brand, size etc did you get (or did you just use PVC pipe) and where/how did you mount it? I had a look today and there doesn't look like there is muc room under the tray (styleside). I am not sure if I will get a pump or just gravity feed the water out. Thanks for your input.
