yr2017 you are the first one I have heard that says the new Rams rattle. The one I test drove was as quite as my Dads 2013 Caddy and it was an Outdoorsman.
As far as the Grand Cherokee goes, those things can be ordered with more skid plates then any pickup truck ever built. Front suspension skid plate, fuel tank skid plate shield, transfer case skid plate and underbody skid plate! Along with a much better four wheel drive system too. So unless your running over pot holes at 35 MPH the GC is better protected then the trucks you list in your sig. But to each their own.
