Rear A/C Question

I am about to order the 148" Medium roof Transit. I will be upfitting it with the maximum amount of shelving I can jam in. I am ordering it with the rear a/c option. I know that the rear air unit is mounted on the floor in the rear left corner of the cargo area. I would like to know how far the unit sticks out in to the cargo area from the left side of the van? I especially need to know how far forward of the rear door does it take up floor space.

Thanks to anyone who has this set up and can take measurements for me. If it isn't asking too much, while you are measuring could you please tell me how wide the cargo area is 60" above floor level?
