The secret to life is Plan "B".Road trips definitely won't be as care free as they were in your Tesla - at least not yet. I do believe that will change rather quickly. Most truck stop' gas station chains have EV charging deals in place and installs are happening. Many fast food chains are doing the same. Rivian's network is slowly growing but it's very good where you can find them.
That being said, if you don't mind putting in some extra planning you should still be just fine. Tons of people here taking cross country road trips and going places off road a Tesla could never reach. At this point, best practice is still to plan your overall route, then check your charging stops on Plugshare to be sure they are working, and then use the Rivian navigation to only route yourself to the next charger. Unfortunately you still need to have a plan B in mind just in case Plugshare was wrong and you need to find an alternative nearby.
