Should I drive my older car a long distance trip?

Hi all, I’m nervous to drive my 2007 Toyota Highlander Hybrid Limited 484 miles to Pittsburgh. I’m moving from Chapel Hill, NC and It’s already at 320,000 miles and it costs too much to ship it. I got a new timing belt and water pump around the end of 2022, but the problem is I’ve been using it for gig driving a lot, and I’m worried it will fail on me driving for 7 hours. What do you think I should do? Would it be worth it to drive or is it too risky? I will be getting two new front tires and an oil change if I do drive, but is there anything else I should check?

Update: Made the drive to Pittsburgh and it went incredibly smoothly :) thank you all for the support and recommendations, it definitely went a long way!!
