Am much as I would be happy with that it needs to look a little better than that.1000litre IBC. Fit in the back of a truck or on pallet forks so you can lift up to height of diesel tank.
They do look smart just wanting to know if there there it a way of doing it without it being trailed.
Spot on one of them would be ideal.
Get a purpose designed low and flattish plastic one if its going to spend most its life back of the truck. Something like a Cemo, Titan or Emiliana Serbatoi. It will be lighter with lower centre of gravity, easier to move about and doesn't really need the extra security and protection a metal skinned tank provides. They'll also be setup with pumps and hoses and have lids to stow it all away securely.They do look smart just wanting to know if there there it a way of doing it without it being trailed.
