I'm posting this here because I don't think I need to hear solutions from those with trucks dissimilar to mine.
What I'm considering doing is working up a way to secure a carbine behind the rear fold-down seatbacks. Removing the plastic and grinding off the kid retraint hooks, and either figuring out a way to lock the seatbacks in the upright position or having some kind of locking cover fabbed up to secure the area.
Thoughts? Anyone else try anything similar? Any pictures of the plastic stripped out back there, perhaps from a sub install? Any measurements of what I'm looking at in terms of area?
