Its unlikely a parts issue as you can order ORG + Etorque with the 6.4 bed. I'm told the ORG is no longer able to be ordered with 5.7 beds when combined with Etorque due to weight issues and the impact on MPG ratings.
If it was a weight issue why would they allow it to be ordered with the heavier truck? The 6'4" bed truck is 100 Lbs heavier than the 5'7" truck with the exact same suspension and reduces payload from 1780 to 1680 before other options are added reducing payload further.
