Help for a long journey in my 2000 Camry

I got this 2000 Camry back in october from a friends grandmother because she didn’t need to drive anymore. I’ve been driving it since and it drives perfect nothing wrong with it and not even at 100k miles yet and one owner. I’m about to take a long trip for vacation in a few months and me and my friend are taking this car and i want to know EVERYTHING i should check before going. It’s over 5,000 Mile round trip from West Virginia , US to Vancouver, BC , Canada and back. I just want to know everything i need before going car wise.
