Two years in a row I ended up mailing my excess packing back from BC to my home
"Why did I bring all this ####?"
We gotta talk.

Hell, when I did the Trans Labrador Highway, I even packed tire irons, spare tubes, a clutch and throttle cable and other emergency items in my cases, along with a mosquito net so that the critters don't haul me into the woods if I got a flat tire.
You don't need a massive change of clothes. You bring a few of this and that, a zip-lock bag of laundry detergent and quick drying clothes.
