My vehicle has too many issues for me to trust it 100%. If I could replace it, I would, but that isn't in the cards for a few months, so plan B is in my buttpack around my ribs for use as a chest rig, my backpack against my spine, and my boots on my feet.

Even if my car was in topflight shape, that would be plan B. And at each break, fresh socks. Fresh socks are good. Even if they can't be fresh fresh, tie/clip them to your ruck and let them dry.
