All good suggestions, but as to helping with the launching; offer to either help or get out of the way. I’m accustomed to launching my boat by myself, and well-meaning guests have made launching a lot harder than it should have been!

My buddies always try to pull my boat on to the trailer with a rope no matter how many times I have told them it's impossible. One of them even refers to it as the "Arkansas method" hahahah

The op had a specific question, not a over all general question about being a back seater.

3 anglers in a 20' bass boat, 2 are younger angler with the boat owner being the experience older bass angler. This is a training outing for the 2 youngsters and should be an enjoyable trip.

Have a good time and all will go well.

The words "General Expectations" were literally in the title of the post.

Ask before shooting videos or taking pictures and posting anything to your social media accounts. If this guy is a tournament guy, he doesn't want to share with the world, he is just sharing with you. And if he finds out you put stuff out there without asking him, it may be the last time him or other guys even think about taking you with them.

 

I'd say if you aren't sure whether to bring 3 or 5 rods, one or three tackle bags, your big plastic cooler or a small coolie bag with a few drinks and some snacks, etc, opt to go for the least amount you can. If you make a good impression this trip, there may be more and he'll let you know and you'll figure out what the rules of the road are fishing with him.

 

And as I am getting to this topic pretty late, hope you had a good time if you already went.
