I agree about how useful the MFT is. Our current 2020 Limited has both the Rambox and MFT. It’s a great combination, especially for old guys lol.'
You might be right, but I don't care about the portions of the tail lights that wrap into the tailgate. If the structure is the same, which I'm pretty sure it is, and the new electrical architecture is designed for the same sensors & latches as are in the original MFT, I'm thinking there is a possibility it will work. Of course I realize it might not work, but for me losing the MFT is a deal-breaker - I would just keep my 2020 Laramie Longhorn EcoDiesel and buy a standalone generator for the house. I'd definitely prefer the EREV truck, but at my age and with my lower-back & knee issues, I can't live without the MFT.

As far as swapping goes, I have no doubt that the MFT will fit the opening. But the latches are different for sure, just like with the current 1500. I have no idea about the electrical aspect of such a swap. I’m sure it could be done. Just not sure what it will take to do.
