I always see these things in the country, I don't know how they build these redneck truck bed trailers, but they look like total scrap in general. Someone offered me one for free (i'm currently looking for a utility trailer).. Unfortunately I had to decline.

Here we have some beautiful examples of a trailer being made from a pickup truck bed (or a pickup bed being made into a trailer):

Call me redneck, but this one is pretty sweet:

Now, maybe it's because they didn't use the full bed or because of the huge tires, this bed trailer actually looks pretty cool.  

How do you build a trailer out of a truck bed anyways? I guess since it's free or extremely cheap people are willing to figure out.
