Modeling the prototype pull harness. (Back)
Once again, a planning error is revealed - an inverted Y will be needed to accommodate tails. The pull ring in back is rated for stupid amounts of pulling - testing shows that the plastic buckles give out first, after a rather disappointing 200lbs or so of pressure. Even still, 200lbs/puller is well beyond what I expect to put these through, given that I added wheels to the pulled items.

I have an order in for buckles using a different kind of plastic, one which is supposed to have 2-3x the break strength (probably a more sturdy design, too).

Background:
At RF, I had people pulling me around on a kennel, but it was a very spur-of-the-moment affair. The pickup truck tiedown straps that were used at the time caused a bit of shoulder pain (didn't spread the weight around at all).
This is my nod to the original pull team - the new team will be much more comfy.
