Great link, but...Did I hear him say the rucksack weighs 55 lbs?
Ooof.
For real, I hope whoever he is rescuing is near his vehicle. Thats just a little overkill. IMO
Thats plenty of Gear for two men, why not just split the weight, travel in pairs, and cover twice (or 3x) the ground.
I am a big fan of "the more you carry between your ears the less (gear) you need on your back"..
