Here is my thread where I will post pics and progress on the two Hennessey clones I will be making, just to keep it all in one place.
Last night I ordered webbing and rope from Backyards Daydreamer. Thanks to everyone for referring me to the site, he had exactly what I needed.
We also watched a movie and ripped the zippers out of our retired 6-man tent. They are really nice long 2-way zippers, it took a long time. I'll upload some pictures this evening.
