I went back and looked at some of my packing lists from my various trips. My gear load when I did transcontinental in 1977 was nearly 50#
some of that was spares that I don't typically carry anymore. Also somethings in the equipment list have been replaced by lighter more modern items. In 1977 I was lugging a Svea 123 stove and a quart fuel bottle. Today I carry a Triangia/Clikstand combo and buy fuel a pint at a time along the way. That is over a pound in savings right there. I have done similar things with sleeping bag, tent, tools, etc.
