Xline do a  45litre trolley,  facelift do a trolley that's 60l and I'm sure you could get or make a bigger one if it was required.

If its a standard 25l one you want then I would look no further than the nano.

The problem with theses bigger trolleys 45 ltr is their weight getting them in and out of a vehicle and moving  them is difficult

I built 2 100 Ltr ones for a hospital job that had over 20 courtyards

they worked a treat - filling was done outside the van via a 1000 ltr IBC - just open the valve - used to fill up in 2 minutes or so
(little slower as you got to the lower part of the IBC
