Advice on what's needed for Wfp for van

Afternoon people,

Basically just starting out, have business registered and have flyers on the way.

Have decided going to use the Wfp. Looking for advice and tips but mostly looking for best way to set up the van? Using pure water, what's required  pumps, reels, etc.

Cheers in advance.

Welcome onboard, lads will chip in but also have a good read through the various forum/topic boards
