The mobile home had her first outing since being parked here at christmas, ticking over like one of Basils clocks, bedroom almost done ,and shower had to cut horizontally to get it in, refibre glassed and is now awaiting the pipes Am mulling over tanks to install, S/S, plastic, and also where would be the best spot to install, it all comes back to the dollar dont it
For water tanks, I am considering those new rainwater "bladders". They fit to most shapes, and collapse. Not sure on the durability for "on the move", but it would save having to get special built, to fit a space.
