OK, for any and all of you out there that ordered the Trailer Tow Package and needed/wanted the TTPMS....if your POC has the version B (and even some that don't might be switched)....I received a communication directly from RAM that it IS a supplier issue that it's been temporarily removed from the truck. Supposedly it is both the wiring harness in the truck AND the instrument cluster that are lacking and they can't get the correct parts from the supplier at this time. It was made clear to me it will NOT be retrofittable later after-the-fact. I was advised to cancel my order and wait until it becomes available again and/or as soon as supply can be re-instated the feature will be added back to the trucks going down the line at that time.
It's very disappointing for me but I'm not in the position to cancel my order at this time as I've already turned my key fobs over for the 2020 and nursing the old Mercury Mariner along for the time being hoping it doesn't die on me until the new truck arrives.
I was told RAM is doing EVERYTHING they can do to keep the assembly lines running to full capacity and try to get trucks to all of us as well as dealers that are DESPERATE for inventory to sell and so subsequently some hard decisions are being made feature-wise (or lack thereof) to keep lines moving.
Just FYI for those of you that this matters to such as myself.....I guess I'll cross my fingers by the time mine is built they're able to source components again and/or that we find this is doable later with Alfa-OBD or something of that nature. (Or sub-harness, module, etc.)
