I would speculate that phase 1 is to recruit local truck drivers first. Phase 2 would be to fill the ranks with non-locals. Thatīs whatīs happening now. The same might be required for the vehicles.
Getting the supplies to PR may have had higher priority as the truck drivers canīt haul the cargo if they donīt have any.
