I recently retooled my platform in the tacoma to better fit the storage containers i use and make more available room. I would highly suggest anyone with moderate woodworking skills (tablesaw access) build engineered i-beams instead of using dimensional lumber. these ibeams weigh about 60% of the 2x10's that they replaced and are much stronger. i lowered the platform and had to do a bit of custom sanding to make the platform fit nicely around the top of the wheel wells but the extra inch and a half of headroom makes all the difference in the world!these pictures aren't the best, i'm heading out tonight for a weekend and will take some action pictures of things buttoned up and fully expanded this weekend.(ps, if anyone knows how to make these show up inline instead of as links let me know!)
