I'm reaching out to get ideas for a tear down, portable backstop that will fit in a pickup bed and can be assembled reasonably quickly by one person.

Not a target or target stand, that's already taken care of. But not all the places I've set up have a large enough area to negate the need for a backstop.

Primary users will be beginners drawing recurve bows up to but not exceeding 30#, with occasional, more proficient users demonstrating with recurves ~45#.
