Look at London Drugs, Future Shop for a dock with the features you want. It won't be built in, but you can have it in the trailer, or at home or the beach. And, if it breaks, you won't have a hole in your trailer.
I have an Altec-Lansing iPod dock. Has an Aux. jack too, but no USB. I also have a Sirius Executive Dock for my portable Sirius satellite radio ( it also docks in the RAV ). Downside of Sirius is the monthly subscription, but it's what we listen to most since we don't camp in places with a lot of AM/FM choices ( or any ).
I would like to add exterior AC and DC outlets to the trailer, but I just put up with extension cords run out a door or window.
