This is a camping unit I built based around the basic idea in this video: http://www.youtube.com/watch?v=jO87kCU5lvU It worked out pretty good!
simple portable table for cooking - Second Generation Nissan Xterra Forums (2005+)
GRANDBY POP-UP (8.0' LONG BED) - Four Wheel Campers | Low Profile, Light Weight, Pop-up Truck Campers
You don't need an RV to have a road trip! Convert your truck into a home and do truck bed camping instead.
Cheap alternative for camping - Expedition Portal/ use the truck bed for a bed!
Good build ideas to offer RV'ers. Built custom to thier rig. I would thing a soft white wood like poplar or aspen would work well.
Toyota Truck Bed Camper Build ... a different take, i like it!
