The Power Wagon shouldn't have been impacted by the chip shortage. When RAM did their press release on the package modifications due to the chip shortage, there were a few models listed as not impacted. It was primiarly the higher trim models, which makes sense because no one is going to buy a Limited or whatever, missing top-tier specs.
"The note to dealers stated that Limited Longhorn, Limited,
Ram 1500 TRX, and
Ram 2500 Power Wagon packages will remain unchanged for the time being."

I think Canada just gets the short end of the stick for some reason.
