Since my van has factory dual AC I "briefly" thought of modifying it to run on 110 Volts and then adding a high-capacity alternator in place of the AC compressor, to end up with similar operation to E-Trek, except just one AC instead of two. I just couldn't justify the cost for all the modifications. However, if done that way initially from Ford factory it would be very affordable.

That alternator driven by a belt on the engine is drawing anywhere from 1 to 5 HP from the engine. This means the engine must run at higher RPMs to maintain the same speed over a given distance. The running at higher RPMs means the MPG rating on the vehicle decreases which has an impact on "Ford's" compliance with US Gov't CAFE standards. This means that Ford would have to find other efficiencies to maintain their compliance with the standards and those efficiencies may or may not be available. Since Ford does not design the body they cannot improve the aerodynamic characteristics of the vehicle. I guess they could install tires that have no grip and thereby reduce friction.
I would not assume Ford could do something more affordable. Government regulations in other areas may create a situation whereby what you are asking for is beyond reach.
