What major issues should I start to lookout for? I just hit 200k

Got my KJ back in 2018 and it had barely 90k on it. It’s been all over and has driven me to Utah from NC and back. I’ve got another cross country trip planned for November, and this time I’m permanently moving out there. So what should issues should I look out for/have a mechanic check before I leave?

I’ve already replaced the fan, water pump, and the AC compressor. Now the only issue is I have a slight power steering fluid leak, but only if I leave the steering wheel turned while it’s parked. Other than this what should I be on the lookout for?

What kind/model of vehicle???
