Doesn't make any difference what it is car, truck, camper or whatever, they only make "X" amount of different lock/key sets. So for example, on an auto assembly line every 100 vehicles will have the same key. It would be almost impossible to have every auto have a different lock, there are just so many combinations for the tumblers. At least on 5th wheels every lock I've seen for the front basement has a "721" key.
