I would say no, since it is bolted to the rack, side panels, and body (under the windows) to keep it as secure as possible. So no matter what, it'll take a little time to disassemble.
ahh bummer, would be sweet if it had an interior panel that could be easily removed from the outer frame. I’m sure most people add them and never remove them, but there’s been quite a few times I’ve wanted to remove the barrier for larger cargo. Which is a huge PITA with the Speski unfortunately
