I’ve just bought a 2020 Raptor built in June this year and I’m in south Texas. Bought the truck with 10 miles on the clock and only a little over 400 miles on it now. There’s already surface rust on the rear diff and the driveshaft pinion yoke (I think that’s what I’m looking at...). Shouldn’t the full underside come treated with some sort of rust inhibitor? My previous truck (‘18 Toyota Tundra Platinum) came fully treated underneath to prevent this and if seemed to hold up pretty well. I would have thought rust prevention would be pretty high on a vehicle aimed at desert running? Anyone else experienced this and any joy having the dealer resolve and treat it?
