Longest Boxster single day drive

[kk2002s]

My longest drive was last year, N.J. to Outer-Banks N.C. - 400+ miles, 7-8 hrs. At the end it was hot and stuck in hour + stop and go traffic. Pretty much worst conditions at the end of long drive. The boxster gave me absolutely no problems in either direction. I had about 60k miles on the odometer then

Now I'm contemplating driving to upper Florida, 950+ miles, I-95, in a single day 15 hrs+
Coming back I might do a 2 day so I can drive some nice roads back maybe Skyline drive (I know it's 35mph)
I'll have about 67k on the car.
It would be on my new Spring oil and filter.
I'm on new plugs and belt.
So I can already hear "...replace water pump...replace AOS..."
So what have others pushed their boxsters too and what did they do ahead of time
