It does seem that there are box trucks based on the Ram pickup chassis, but I don’t think I’ve seen those in person. Most box trucks I see here in Canada are either based on a van chassis (usually Ford Econoline or Chevrolet Express/GMC Savana, but sometimes European-style vans like the Sprinter), the Ford F-650/750, or an actual truck chassis, like an Isuzu cabover or something from a company like Kenworth or International.
I agree. The peaceful people in Russia don’t deserve to be invaded. Pity there’s not many of them, though.
