I managed to put the new canvas on by myself with the exception of slipping
the canvas over the frame with the help of my roommate.  I did NOT remove
the pop-top from the van.  I started at the front, also securing one screw
in the middle of the back to ensure I was using equal material on each side.
  It took me roughly 10 hours over two days, but would have been much
shorter if I had not put the bottom rails on the wrong sides!  I started
both of them at the front, and when I got to the back realized they were
reversed.  I undid all those dang little screws and put the rails on right.
The front corners were tight but doable.  I propped the pop-top partially up
with a piece of wood so it was not fully extended.  When I got to the back
there was a little extra material left.  Although I did the job myself, I
had advice from my roommate who had done it previously.
