thats a really nice build. I have an extended ford and was thinking of doing the same thing although my carpenter skills are minimal at best. Did you have to put paneling on the sides to get the carpet to stick? How much did it cost you to build that?
To tell you the truth, you don't need a whole ton of carpentry skills to do something like this. As long as you don't rush or get mad when things get a little tricky you will be all set. I know hardly anything about this stuff and don't do anything like this for a living, but I am lucky in the fact that my father works on the show This Old House. Just ask someone you know who knows this stuff a few questions about how to do a few things, like building a wall, and you be good. As far as putting the carpet on the bare sides, I don't think it would work. The glue probably wouldn't want to stick to metal even if you roughed it up first, and cold temps would probably make it bubble and come undone. One of the biggest reasons for paneling the sides is to keep the body from getting dented. It is a lot easier than some people think to make a dent from the inside pushing out, especially in the cargo area with handlebars and such. Plus, it just looks a lot cleaner too. I kind of went overboard on this build and spent between $2000-$3000, but in the long run it is well worth it.
