Sounds like you had a Great time!
Sliding window on passenger side of our coach whistled too. I sprayed the felt with silicone spray and slid the window back and forth, slammed it closed a few times to seat it in the felt better, no more whistle and wife says it moves easier now. Did drivers side the same way.
I keep saying I'm going to buy a locking gas cap but haven't done it yet, going to hate losing the tether.
