You sure you dont mean your vans 8 ft 10 high?
Ocado vans are 9" 11 high and 6" 10 wide.
Im sure there the tallest delivery vans for a supermarket on the road■■?
The Transit I drive is a touch over 9ft 4" tall (3.5T Luton), I know as a bridge in Natland is 9ft 6" and I literally take the paint off if I use it 
As for width I’ve never worked it out, but the body is about 3" wider than the cab on each side.
Just to prove im not going mad this is the sign in my cab. I know its not 100% accurate as have been under a 9ft 9 bridge and the van is still intact but its a guide
