After some observation there seems to be two different Deluxe Panel Trucks.
The 1st Deluxe Panel truck does not have any rear doors window stainless steel moulding. At 11:12 into film.
The 2nd Deluxe Panel truck has rear doors window stainless steel moulding. At 12:43 into film.

I thought maybe they used one Deluxe Panel truck by editing the film.
I guess Not.
I don't think the director of the film thought anyone would notice.
Some scenes show that, the robbers and the flower delivery man were driving both trucks.
