Well dang, about 90% sure.
Because the standard 13.5K A/C/heat is in the mid position if you only have one unit. Also, the front A/C came with a nice digital controller, not the analog controller like the standard equipment unit that has AC and heat. Thanks...now I am going to have to get on top and take off the covers to check for sure, because it is going to bug me until I verify it.
But I would bet a $1 that dealers don't take the time to move the stock unit to the front and then add the 15K to the middle; it was a Diamond package from the factory, so you my well be right. I did change the main AC/heat to a digital controller so they would play nice with each other and it was a big improvement, MUCH less swing in temps now.

Youroo!! 
It would be nice to just swap them and let the larger unit doing more of the work. Glad you asked the question, I'll watch for other responses.
