I considered putting a hinged door in the kick panel behind the drivers calves to access that area, like someone did on the P1's, but I have my second battery there and don't need to get in there very often.
As for switches and such, my dash is full. Even opted to use the supplied adhesive backed switch for the new pods as opposed to drilling another hole.
Saw the door bags years ago but really don't want anything making the cab any more confined than it already is.
This idea I'm kicking around now utilizes dead space, not that there's much in a P5 but it's there. Cargo bag is good for small items as is the glovebox. Console holds a little more but I put all my personal stuff in there for a ride, EDC, wallet, cell phone, cheater glasses...it just fills up fast. If it works this will be an 8" x 16" tight knit cargo netted area with a void behind it. Under the dash and under the glove box area. You might touch it getting in and out but that's about it. That's the plan anyway, the execution is yet to be determined.
