Playing With Sound

[Muskie]

Hi Folks,
I am curious if people have been experimenting with sound and speakers, or musical instruments inside their Airstreams. I have a 59 Tradewind that I converted into a traveling music studio, and have recently been recording inside it using multiple speakers and microphones. The curves give it a natural whisper-sound-throwing effect.
I am curious if anybody has had similar experiments or experiences with speaker placements etc.
My video is here;

Cheers, and interested in audiophiles that tow these beasts around. They are like mini St Paul's Cathederals!
