I had a tent that I started to convert. I became very bus halfway through packed it up and never opened it again.
Moved to SA, and now I think my wife got rid of it before coming over 3 months later. Below is a link to the progress I made. It worked well and was enough room for me to sleep in as well. Just never go to complete the fly cover section.
