Did ours last fall, sourced the top from
Tough Top. Good directions came with it, does IMO require 2 people, my wife held the fabric up and I pulled it, worked well, gets really tight toward the end of the 15' run on the LR slide. Here's a link to a thread with pictures of the job.

EDIT: I got a strap wrench from Home Depot, made twisting the roller very easy.
