One of the biggest improvements to my packing has come from incorporating the Box Hitch into my packing arsenal. Basically this is a hitch that is designed to lift the panniers up and slightly away from the sides of your pack horse.
I was taught by my uncle, Colby Martin, but he is kinda camera shy. So the next best thing is a video by Todd Jones from Casper College. Todd is also an outfitter operating Paintrock adventures in Wyoming.
Watch and learn folks!
Now a note on what I do differently.
first, I have the hook on the Left side. Todd shows it on the right side. I like the idea of putting the lash cinch under the cinch connector on a two cinch sawbuck.
Second by having the hook on the left, my tie off is on the left as well. That much easier to get to if I have to bail off and untie the lash rope in a hurry.
