In the 2004 screenplay, Jack joked about eating beans and sleeping in a zipped-up tent:
EXT. BIG HORN MOUNTAINS, WYOMING: CAMPSITE: NIGHT: 1973
ENNIS
Hey, look what I brought.
He offers a small brown paper bag.
Jack weighs it in his hands, opens it.
It's a couple of cans of beans.
JACK
Beans.
ENNIS
And I'm gonna fix 'em just the way you like 'em, spoon 'em cold straight
from the can.
JACK
I'll eat 'em from your hand, if you're willin' to breathe the consequences after
that tent gets zippered up tonight.
A beat.
