Mm5 I know of people ditching their Vivaro due to only getting 70 range but much of this is due to driving I so far have not experienced huge weight difference we have a hoist a 150 kg chair dogs, but the base vehicle is heavy so perhaps weight isn’t so important. Driving style on the other hand truly makes a huge difference but we had to go electric due to cost so always pulled the most we could from a diesel, so if you have that approach with the electric. But wait times are massive so we found a cancellation but even that’s not easy anymore.
I am the carer / driver for my wife who cannot drive due to disability
