For having one setting in the middle of the desert and only one other person there with you, there's a surprising number of items you can find in this chapter. First, deal with Lenny. You don't have to kill him, you can simply subdue him. Do so and you can take the Swiss off of his body. You are free to leave at this point if you like but lets get the rest of the weapons
Grab the four guns out of the car, Destroy the stagecoach to collect a fire poker, check the marked grave nearby for a bong, check Lenny's grave for a dog bone. There's also a Tomahawk imbedded in a nearby tree and a Wrench mixed in with a small pile of stones just beyond Lenny's grave.
