I've seen pickups with various types of bed covers:
Soft tonneau
Hard tonneau
Aluminum caps (shells)
Fiberglass caps (shells)

Are there any other options? I want something that goes on/off easy. I won't need it on there very often, just for trips to keep luggage out of the weather and locked in. I've thought of a truck tool box, but they're not big enough to hold even 1 regular suit case. I was wondering if there's anything like a car roof top carrier that could be put in the bed of a pickup? A hard tonneau would be good, but they are pretty pricey.
