Water shortage (1 Viewer)

[Warmleys]

We are looking forward to 3 months away in our motorhome. I can see a potential problem though. It looks as if camp sites will be fully booked this summer so getting fresh water for our tank. My idea was to get a couple of big water bottles and buy a submersible pump to pump it to our tank. Does anyone do this or is there a better way.
Thanks Rob and odette

Has anyone found a collapsible water container with a neck that will accept a submersible pump?

This one but only 8 Lt & expensive.
