Good Morning All,
In my humble opinion, my #1 priority would be to rent a small garage/storage facility space (one with electricity to connect a Deltran Battery Tender), so it would be protected from the elements—and trickle charged.
Rodents are not a worry unless you have a vermin issue in the garage.
Other than the garage and trickle charger—you can for peace of mind dump a reputable fuel-stabilizer in the tank if it makes you sleep better. If you put your Raptor in a garage/storage facility space—you’ll be fine.
NOTE: Gasoline (even w/ethanol) is fine at 3 mos. Purely science with data vs. the anecdotal.
All of our vehicles (including RV) are in our garages—and needless to say, that is the way to do it. I have a ‘70 muscle car that belonged to my uncle (he’s still in good health, but sold it to me). He garaged it since buying/restoring it 25 or so yrs ago and I’ve garaged it since. Looks brand new as a result.
NOTE: I know for some the Raptor is “just a pickup truck”, but some do prioritize keeping it looking good.
