You're overthinking.
Go, park your truck, wipe off the latest bugs or smidges, shine your tires if you haven't. Pop your hood and door if you choose then go check out the other rides.
When you're tired of walking and/or talking go back to your truck, flip open a chair and kick back. BTW the last steps can be reversed.
Be cool and helpful to anyone who talks to you, and ignore any negative comments.
