In my opinion yes, I would hold out for a newer build date. All other things can be attended to with the recalls but not the cab mounts. "Beginning with the 2019 models built after July 2018, the cab mounts to the vehicle frame at the C-pillars were strengthened to improve occupant protection in small overlap frontal crashes."
Naw, not much you can do about it now so no need to be concerned. Trucks are pretty safe in general but they did strengthen the roof a bit with the newer builds. Hopefully you will not get into any major frontal crashes but should still be safer than older trucks I would presume: https://leftlanenews.com/ram/1500/redesigned-ram-1500-improves-crash-test-ratings/Well, I own it now...….lol Should I be concerned about the above items? Is there a recall to fix? ( I didn't see any) I havent seen a definitive production start, some said Jan of 2018?
