Yeah I have the weather-tech style RAM mats, not the fabric ones. This was the first time I took them out of the truck to give them a good scrubbing and a rinse off. So yeah almost a year has gone by before finally noticing it. I would recommend anyone else do the same, you would never know it's wet under there. I hope for the best, I have a very good dealer and rapport with the service department. I've done a lot of work on the truck in a year too (rolling aluminum tonneau cover , debadging, ceramic coating, new black rams head logo on tailgate and black RAM grill letters, new all black sport hood, added side step bars, tinted side windows (this is not the cause of leak - tinting today does not required the door to be taken apart). So it does sicken me that this is the beginning of unsolvable problem.
