For trucks X and Y the optimal aero-mod may not be the same solution.

yes,very much so.When Sport Truck Magazine did an article about pickup aero they had quotes from the truck division guys from at least the Big-Three,who emphasized that pickups should always be considered on a case-specific basis.
