There are millions of trucks and SUVs roaming the highways of North America. Loads of otherwise perfectly capable trucks will never be driven on gravel roads for fear of scratching/chipping the finish. They will never haul so much as an empty cardboard box for the same reason.
The late model (mid 90s) Chevy Suburban on the right may well belong to this group. The 1983 built M923 5-ton cargo truck on the left, however, spends lots of time roaming unpaved areas carrying heavy stuff that might or might not be anchored to the bed. That cargo will eventually be dragged across the bed and likely smear/chip some of the paint off with it. The state of the bodywork? Nobody seems to mind the minor dents, dings or surface rust. The paint isn't just non-shiny, it sometimes feels like sandpaper! I would actually like to have one of these.
