Namaste

Take a 3 season bivy sack and a your normal sleeping bag. It's pretty uncommon to not find some shelter in a densely populated country like Nepal, but stuff happens and better to be a little on the safe side. Stove would be totally a luxury thing though, wouldn't bother to bring. If you feel you want a stove, make an alcohol stove on tour.

Personally, I question why I am carrying a full camping load here in Vietnam at the moment, but I've had to camp it out a few times when the weather went sour.
