Bigger water tank , or additional one

[Ridgeway]

Changing or adding a tank
Seems a lot of expense & faff to go to rather than topping up with a couple of watering cans a day.

If only, a couple of watering cans lasts us a few hours.....

We too long for a 2nd water tank and i may well add one into then trailer and then just pump it across when needed. No weight issue and less of a space issue, just need to get my finger out and get it done. I'd be happy with another 100ltrs so probably a flat tank with top bulkhead, i have a spare in the barn but it's 220ltrs and just tooooooo big, would need it's own trailer
