In order to trigger Borderlands 2 Clan War: Trailer Trashing we have to speak with a man near the exit point from The Dust to The Highlands (the yellow exclamation mark on the map).

Walkthrough
After we get the mission, Mick Zaford instructs us to go to the Hodunk trailer park in The Dust area.
As a side objective, he wants to go there at night; therefore, we can wait for the night to come, or we can go directly if we dont care about the secondary objective.
When we arrive at our destination, we need to search for four gas tanks (marked on our map) and open them, after which they have to be destroyed using a fire weapon. Some enemies will spawn during our mission, but its nothing we cant handle.
After we successfully destroy all gas tanks, we need to return to Steve (the one who gave us the mission) and turn in the Borderlands 2 Clan War: Trailer Trashing quest to him. We can now go back to Hodunks base to get the following mission in the series, Clan War: Wakey Wakey.
