I'm a novice but...
I made one just like guthook stated from his post... (http://www.theboxotruth.com/docs/edu24.htm)
It's actually quite easy to build, cheap, and very easy to tear-down and put up, and quick too.
It only costs about $10-15 and you can pretty much put into any vehicle you...
Woohoo!
Just got mine finally! Good to be official :party29:. They send a BUNCH of stuff with it though, it came the day after. I guess I know now where my $30 went!
