Nice looking family!
I do have a question though and I'm not trying to be funny. Is that a speaker or a head rest behind your family?
If it's a speaker, did you ask the dealer about how water tight the speaker is. I've had my tub overflow when we all got in and I wonder if something like that is covered under the warranty. I don't have a stereo in mine but the speakers would have definately been under water if there was one.
Enjoy your new tub!
