Same with Sirius. Buy a new car, then get useless Sirius junk mail and emails forever. We don't use Sirius and don't need it on cars.
If we need or want something, we know how & where to find it. I don't remember ever buying something because we saw an ad for it.
Interesting that the SR5 rode very well for you. One of our forum sponsors @alldogsoffroad said this about his SR5, " The OEM SR5 suspension was really, really not great. " He changed to their ADO Fox Suspension which was a big improvement.
I love most everything about my ORP (non-hybrid)...

These LT275/70R18 E-rated Toyo AT3's are perfect for our needs. Thought about 285's, but didn't want to create rubbing or spare storage issues.
We ran LT265/70R17 E-rated Toyo AT3's on our 2020 Ranger for 5+ years, often aired down off-road. They were great both on & off road. Still good gas...
If you want a matching spare, consider whether the 285/70R18 tires you are considering will fit in the spare tire cavity.
I almost went with 285's. But stayed with 275's on our TRD PIO +45 option wheels.
I have five LT275/70R18 E-rated Toyo AT3's. For this tire, it appears to be the max size...
Those are great running boards.
I'm usually not a fan of running boards. However, our ORP OEM fixed boards have good grip, work well for stepping in & out, and stop crud from being tossed up by the front tires.
If I need rock sliders, then I'm in where I shouldn't be.
