Hi everyone. We just bought a 2022 Tiffin Open Road Gasser. V8. Lots of folks and the dealership say FULL SYNTHETIC while Ford manual says SYNTHETIC BLEND. We live in Arizona. Won’t be traveling in cold climates. Planning on short trips under 5 hours with a couple of longer summer trips to the Pacific NW towing a Jeep Cherokee Trailhawk. Opinions appreciated.
