I am a big fan of doing your own wood. It does not take a whole lot of woodworking skills. We sell wood kits and all the parts. Don't get me wrong I don't mind selling them. It boils down to time. If you need fast buy a kit. If you can cut accurately on a table saw and have the time. I say do your own.
Its fun and you can have even more pride in your truck. I have made beds out of trees that I cut down (red oak) dried myself and planed my selftalk about a long time
Like said above you can make it out of any wood you want ( Indian Ivory wood????) (plexiglass?) the options are a lot.
All you need is a quality table saw to cut the wood, assuming you bought planed lumber. You don't need a router to cut the kerfs on the edges, you an use the table saw for this also. Router? ah if you want to but not needed. A few drill bits. If doing like factory a forstner fit for the bed to frame washers.
a band saw or jig saw to cut out th wheel house openings. .
I would do my own. Its fun.
True alot of it is where you get the wood. There is no stock answer for this as many people have diff sources for diff prices depending on where you live.
I always wanted to make one out of Mesquite. Kind of black and Yellowish
