I have found a really nice and CHEAP accessory that I thought someone might
like.  I converted my Diesel GL to essentially a weekender without the stove
fridge, etc.  I also never use the middle seat.  Thus, i have a great expanse
of wall space in my van on the driver's side wall.  Always wanting more
storage for my gizmos, I founf the "Mighty Truck Cab Organizer" at K-Mart for
$9.49.

Almost exactly the width of the pop out panel and comes with hardware for
mounting.  Made of black durable nylon and has pockets galore to hold just
about everything.  I have nesting camping pots/pans in the two outer pockets,
my mag lite, maps, the dogs lease, etc. etc.  More room still to fill with
important stuff.

This side panel is probably the only place in the van to mount something this
long, so if you have a fridge, you are out of luck, although you could
probably mount to the wooden bottom of the back bed seat as well.

Nice item,  give it a try.
