Good deal orton, thanks. With your DIY good eye for detail, I imagine you will notice lots of other things.
If you do see a Wagon with rear A/C, please check out the intake and discharge grills, as it looks like [photo 5/5 of the van posted yesterday] there is some kind of grill facing forward on the front of the rear grey hump. Guessing this is a supply discharge intended to blow up and also under the rear bench seat. If so, it means that luggage, tools, etc. should not be stowed tight to the grill. In one of the other photos posted in the threads below [or more likely in the video which Rico posted], I saw an oval warning safety sticker on the top of the grey hump, which likely warned about putting heavy objects ON the grey hump, and perhaps also about the need not to block the discharge grill on the front of the hump?
Another dimension it would be helpful to know [again with your DIY good eye -- well done on the Sprinter conversion!] is whether, upon removing the back bench sheet, will a 96" long sheet of ply/drywall fit between the base of the next bench seat and the rear doors?
Also, in another thread, there was discussion about fitting a bed behind the middle bench seat (with rear bench removed). Not sure which wheelbase was being discussed, but it would be nice if a 6' long bed (or maybe a little more) could be squeezed between the bench seat and the rear doors. Picture a single bed on the left wall of the Wagon over the rear A/C grey hump -- that's the picture.
Sorry for the VIF shopping list -- when a Wagon appears on a lot within 50 miles of me, I will be heading out to check this all out!
Come on Ford . . .
These two threads contain the most on-topic discussion of the rear AC hump in case you feel like posting there as well, orton.
Thanks again for any insights and leads.
