The standard tank on a Ducato motorhome chassis now is 60 litres. Until the launch of the 6d engine for 2020 Ad Blue wasn't needed.I believe that the 'standard' tank size for vehicles which use AdBlue is 80 litres, leaving 10 litres for the AdBlue tank = 90 litres in total.
For the new 120/140/160 etc 6d engines the Fiat has a 15L Ad Blue tank.
Ford MH chassis have a 60L fuel tank & a 20L Ad Blue tank.
The new Pug 6D is about the same, it has a 18L Ad Blue tank.
Lowering the fuel tank volume and now ditching the spare wheel is all about payload.
