Bubba,
I have not done this, but the custom shows on TV all seem to use a basic frame made with MDF fiberboard, covered with fleece to define a shape, soaked with resin to firm it up, and then strengthened with fiberglass mat and smoothed with a soupy body filler before paint or covering with vinyl/leather. If you Google "fiberglass enclosures" you'll get a bunch of how-to's on custom speaker & amp enclosures - the concept should apply to your console. Here's one -

Hope your daughter enjoys her truck - maybe she can help you decide on how the console needs to look!
