I'd suggest that you should acquire a CCS1->Tesla adapter. There's often non-Tesla CCS1 DCFCs in rural areas and being able to use that charger can make all the difference during a road trip. Likewise make sure you have a Tesla mobile charger in the car with NEMA 5-15 and 14-50 adapters, at a minimum, along with the J1772-> Tesla adapter. Rural areas often have RV parks with NEMA 14-50 outlets and they will often allow EV charging (for a fee) and that can fill in the gaps in rural areas. Some places and hotels will have J1772 L2 chargers available.
You can use Plugshare to find all the potential charging locations in a given area, if you set the charging filter to Tesla SCs, DCFCs, L2 chargers and NEMA 14-50 outlets. Make sure to read the comments regarding a given charging location, since that will give vital clues as to it's operational status, Load the Chargepoint, EVgo, EA, etc, apps into your cell phone and set up the required accounts to save time when on the road.
If you find that an EV campground, especially if not listed in Plugshare that's located in a convenient location, phone ahead and see if they'll let you charge there.
You can use the car's web browser to view Plugshare and ABRP, and then set them as favourites in the browser for fast access. You'll need a premium data plan from Tesla to use the incar web browser.
