I found some things in the Northern tool catalog.. I have torn 3 ratchet straps so far, so I know the axle straps would be a good idea. It does seem as though chains would be safer. One of the straps has chains on the end which would be neat to have instead of the "J" hooks. I like the way Conlee straps his jeep down by putting all the chains under it rather than in front and behind.
