Yes, the passenger seat folds down, but it would provide more space if I removed it altogether. And it's almost always just me, so... If I just turn off the Passenger Air bag, then unplug the seat connections, I thought I could just leave it unplugged. I'll check with the dealer to see if that disables the entire system. I would think it would just involve the Passenger side.
The dealer said he sees them removed in their shop all the time. No details yet though...
