I have built several Wicked Ones, but I'm not into car audio at all. I can't really advise on your truck, but I do know good sound when I hear it.
I believe that you will be pleasantly surprised, if you do a decent job building a full sized (thirty six inch by thirty six inch by about fourteen inch) WO. Your carpentry skills give you quite an advantage over many. As long as your joints are well cut, strong, well glued, air tight and you build it to Steve's specifications, it will work with almost any decent pair of ten inch drivers.
It is a fairly large enclosure, but bang for the buck, it's really hard to beat.
I built my first pair out of MDF and spent about a hundred bucks on materials, put ebay, used drivers in them and never looked back. I have since built some larger, more carefully constructed versions and this design has never failed to impress.
Just DO IT!
BTW, no one will criticize you much here. The folk here are mostly interested in helping each other, in order to earn bragging rights.
