- "It looks like Trevor's been smoking more than he's selling again, 'cause we're almost outta cooking chemicals and we ain't sold much Ice. The Lost got a lab in an RV that they keep moving cross-state. It should be stocked with chems, so if you bring it back to us I'll make sure you're paid. R. Jakowski"
The team must steal a moving RV. The team must kill the gang members and steal the RV containing meth cooking gear. Lost MC members will chase the player driving the van on the way back to Sandy Shores, kill them or just escape from them. The player needs to take the van back to Trevor's meth lab where they get their pay.
Chef is seen at the ending of the mission, approaching the RV from the back of the Liquor Ace.
- Steal the RV.
- Deliver the RV to the Meth lab.
- Ironically, the earlier mission Meth'd Up requires the player to steal a Journey from Liquor Ace.
- The name of the mission is a play of the word "crank" (a slang for methanphetamine) and the idiom crank up the volume, which means to raise the volume of an audio device.
