Cheers Craeg. If ya can make it then the bins are yours, plus cash as well if needed. Im not after a complicated design, just a standard type swag with a double layer on the bottom to slide a foam mattress in, full length zip down one side with a flap and velcro covering zip. Oh, and maybe a couple of leather straps at the bottom so when rolled up it can be strapped up. Hows that sound ? will send you a drawing if ya pm me ya e mail addy.
