People forget that the early GM designed trucks were designed to do real work. Dirt was expected. A great many roads at that time were dirt. Today we are spoiled with things like environment controlled cabins. Dirt roads are avoided because it might make those rugged-looking hard to clean low-profile wheels dusty. If you want to maintain a 70 year old Stovebolt truck in a preserved state then a nice clean garage is perfect. When showtime comes, a covered automobile transport hauler to get it there.
