Recently inherited deceased family member's FJ - tips on common issues to look out for?

2008 model. High mileage (212k) but overall seems in good shape (except aftermarket sound system) with new tires.

I used to off-road a lot in the desert with my a 2004 Wrangler TJ, which I loved; driving this the 1200 miles home after the funeral reminded me a lot of that.

I'm in Vermont now, so planning on undercoating it after my shop checks all my suspension and safety inspection components next week.
