Dave is a misogynist who enjoys harassing Karima, another resident of Overlook. He also briefly interacts with the Vault Hunters as they experience Claptrap's memories during the Claptastic Voyage DLC for Borderlands: The Pre-Sequel. In the Claptastic Voyage DLC, he seems less overtly hostile, so it's possible his sour attitude developed after Overlook was mostly destroyed.
In the Claptastic Voyage mission The Psychology of a Claptrap, Claptrap asks Dave where to procure fireworks for the Vault Hunter Tournament halftime show, and apart from a few lines of dialog, is not heard from again in that DLC.
In Borderlands 2, Dave will frequently butt in with disparaging comments during the missions The Overlooked: Medicine Man, The Overlooked: Shields Up, and The Overlooked: This is Only a Test. During that last mission, Karima has grown tired enough of Dave's constant badgering that she "accidentally" leaves Overlook's shields down during the mortar test, which destroys Dave's Shack, sending him tumbling down the cliff.
