1) They are bumpers (mostly ornamental); not storage tubes. The caps are designed to be hammered in and left alone. They could make the bumpers more sturdy by adding weight to the camper that gets subtracted from your payload.
2) Bike racks and spare tire holders twist the square tubes and work the caps out. The solution is to not use them.
Next time you check one with missing caps, look for evidence of a sewer hose, tire or bike rack. You will solve the mystery of the missing caps.
