Not thru hikers, but about 8-10 years ago I saw some backpackers roll into a shelter with 70L packs. Took out a Coleman two-burner stove & 2 pots + 10" fry pan for two people. He used a big 10" piezo lighter/stick to start the stove ("faulty auto-ignition"). Went down to the river for water and came back with a 2+ gallon collapsible water tank full. He cooked up some mean sausages and peppers and mashed potatoes. They set out a plastic table cloth to eat on, took the propane bottle off the stove and screwed it into a huge Coleman lantern that lit up whole neighborhood. They took out a hatchet and cut up some logs to make a fire. She made herself busy setting up the tent (had to sleep at least 4) and inflating the double sized air mattress (battery pump). They were very nice but loud as all get out during all their preparations, and asked if we would want a little music and took out a little battery FM radio. Luckily there wasn't anything good playing and they turned it off. They said they were spending a week hiking the park. It was the end of their day 2 and she was jokingly saying the camping part is fun, the hiking part is too much work. I suggested they try lighter gear next time. They were amazed with my stove, I think it was a pocket rocket at the time. I think they got outfitted at Walmart without realizing they had car camping gear.
