I am not a pro at this- AND I am super poor so my conversion will be cheap using second hand stuff. I am creative, however, so it will at least look pretty cool when I'm done. So far, I have pulled all the passenger seating out of my Dodge 3500 van. Empty!! I have removed the metal frame/legs from the bottom of the seats and re attached them close together in the back to use as a bed frame. I am super proud of myself for thinking of this, because I could never figured out how to frame in a platform with wood. The empty space under the bed will be perfect for storing the few things I don't need to right away, and the height of the frame is just high enough to slide banana boxes underneath. The bed is probably bigger than most, but I have an extended van, and if I am going to live in it for awhile, I want to be able to stretch out. Comfort is king! <br>
