In Into the Wild, how does Franz change his lifestyle after Chris's departure for his Alaskan adventure?

The answer to this question can be found in Chapter Six of
this great piece of non-fiction, after Franz receives his final letter from Chris
McCandless as he sets off for the next stage of his journey. It is quite amazing the
impact that Chris McCandless had on this eighty-one year old man. In the letter he
receives, Chris tells him to move away from the city and head out into the wilderness,
camping and living at one with nature. And surprisingly, Franz does exactly this. Note
how he responds to the letter:

Astoundingly, the eighty-one-year-old man took
the brash twenty-four-year-old vagabond's advice to heart. Franz placed his furniture
and most of his other possessions in a storage locker, bought a GMC Duravan, and
outfitted it with bunks and camping gear. Then he moved out of his apartment and set up
camp on the bajada.

Franz
even occupied his friend's campsite, staying there and awaiting patiently for Chris's
return. Thus we have yet another example in this text of the profound impact that Chris
McCandless had upon others that he met. Franz is perhaps one of the characters who was
impacted most, but it shows us the kind of charismatic individual that Chris was and how
he changed those around him.
