I can’t image using the manual tonneau, what a pain pulling individual slats out and storing them. I have ordered and already taken delivery of the weather tech (Lomax) tri fold hard tonneau cover. A much better option than the Rivian Manual Tonneau in my opinion.
Also a 2019 pre-order, R1T Launch Edition. Currently a February-March 2024 delivery estimate, sure hope that it is moved up given the progress on the service centre and the availability of vehicles.
