John, great idea to go with the Endurance and a TPMS system - piece of mind when on the road. You might want to search out a Ford Truck forum to see what’s required to add it to your truck’s system.
We have a 2019 RAM 2500 and while they advertized the TTPMS as an option at launch, it was delayed until recently (on 2020 models). The RAM truck forum posted the components required to purchase but it also requires one to “hack” the ECM to turn on the computer code. Dealers won’t touch it.
I really don’t want to go that route so I’m looking at a Dill external TPMS with flow-through sensors.
They’re the most reliable and Dill was recommended by another Airstream Forum tire expert.
Hopefully you can just add sensors to your F350. Try visiting your local Ford dealer’s parts department and see if they can help.
