Yes! The RSE steps are damn near mandatory for climbing in/out of the back seat in my 2-door FE. I’ve had zero issues with them and, frankly, can’t imagine my truck without them. Not to mention my seats still look brand new after 2+ years because I haven’t been sliding off of them to get out...
I refused to put flaps on mine. Hated the look. Picked up a couple small dings, but honestly, the Goodyears stop throwing heavily at around 10k miles. My opinion would probably be very different if I spent a lot of time on gravel.
Check with your insurance about lowering the deductible on windshield replacement. We did and it was a no-brainer. Super cheap. I don’t worry about the windshield anymore. I just accept that my day is coming.
Man you will be changing the oil again if you try that maneuver. Get a Ronin plug for your next change. It gives you the ability to drain just a little if you need.
