Welcome to the group Celine. I sounds like you are getting ready for that new adventure inn great style.
Just for starters, and there will be lots of suggestions as well as answers to your questions:
1. Get the age dates on the tires
checked, regardless of how they look, anything close to or over 7 years old should be replaced.
2. And also have the wheel hubs pulled and have the wheel bearings checked, repacked and new seals installed.
All to often these items are overlooked or ignored for years, leading to new owners having problems on a first trip out.
Don't worry, there will be more "Lists" forthcoming....
Good Luck with your New-to-You Trillium
