Hi Scott
My old valeting vans...VW Caddy old shape....Fiat Ducato swb low roof....Citroen Dispatch....Then went back to smaller vans....Citroen Berlingo then a Renault Kangoo..
The reason going back to a smaller van was getting on to peoples drives ways.
I would have had a Vivaro but back in the early days they had gearbox problems up to about 05 reg.
The next van will be a NV200 because they are just that bit bigger but not to much to get on peoples drives.
You might just have to flip a coin mate
