150 lb can move on her/his back average personal character (F, F2). In real world 40 lb backpack is quite a problem, both in the mountains and on a bus. Russian "Masters of tourism" can carry 60 lb backpacks in Caucasus. Are Fallout characters (with 275 lb luggage possible) Sherpa people or weightlifting mutants? Now playing with ST 1 and small frame character. The car helps a lot with luggage. Hope Kilap can fix it.
