Mine is 775 lbs.
I found mine from a surplus dealer in Colorado. He had three left, and now he's sold out.
There are other places, like the site above. Some may need a bit more TLC than others. Mine only needed a few rust repair spots, and new paint.
Then I added all the extra stuff. However, it did come with the tarpaulin.

There is a dealer in Quebec. Name on ebay is Military Tires. Michele Kuntz, I believe is the name.
