I haven't done much one bag travel myself, just a couple weekend or five day long trips, but one important thing is that it's a whole lot easier when you're not obese. I've lost nearly 200 lbs and it has become so much easier to fit everything into a single bag because my clothes are just so much smaller. The bag weighs less too. Or I can fit an extra camera lens in there since that's the primary reason I travel these days. A lot of the one bag travel advice I've encountered assumes that you're in relatively good shape.
