Hello All. Having recently acquired and a caravan chassis I am now planning its conversion into a transporter. I would like to do something like these:

Thinking about getting some U section bent up to make the bed. If any one out there has a Brian James or the like please can you give me the dimension of the U channel section (width and height) and thickness of the material to see if my assumptions are about right.

Thanks for your help.
