Yeah so we picked up a shard of glass or plexiglass at the storage yard picking up the trailer. I recall thinking "what else could possibly go wrong today?" LolI notice the right rear tire is a spare, did you hit debris in the road?
It has an FX4 sticker, so should at least have rudimentary underbody protection. When I changed the oil on my truck, one of the things that I noticed was how exposed everything was compared with my other trucks.
As mentioned, if something came loose in the engine compartment, things can get bad in a hurry. Luckily, changing the antenna shouldn’t have knocked anything loose in the fuel system I don’t know if a small extinguisher would have done much unless you caught it really early. Also, an electrical fire will just keep reigniting while the amperage is still available. That said, it’s always a good idea to have an extinguisher.
Good luck with everything!
