what plan did the three friends make to have a hastel free trip

After compiling a ridiculously long list of things for the trip, George suggests that they bring only the things they cannot do without. The men then agree to travel light, and even decide to bring a cover a sleep in the boat so that they do not need to pack a tent. George promises that it will be easy to wash their clothes in the river with a bit of soap, and J. and Harris trust him (although J. notes that they will later regret this).
