teardrop trailer galley. check out the ikea stuff on the lid. That could be a cool idea.
$85 - Child's Bunk or Large Cabin Shelf: This cleverly disguised bunk slides out 18 inches and will hold up to 100 lbs. With a 10 inch tall bump board, it is the perfect perch for a small child. Without the bump board (and easy access to the build in outlets), it is a great shelf for a laptop computer and other camping items.
Pop up camper conversion. My thought would be to use this idea of a slide out and add one on the other end. Wonder if they need to be supported from underneath?
