Now, more prep for the handyman con. We need a maintenance van and some maintenance to do, something major... maybe we pour hazardous chemicals into the roof ventilation system. I don't know. Just... get a Water & Power van from the location on your GPS and we'll talk.
Lester informs the player that they still need both a maintenance van and some maintenance work to be done at the casino. First, he sends them to a warehouse in Cypress Flats to steal a LSDWP Boxville van from some workers. When inside the van, the workers get hostile, but they can be easily outrun.
Once the van is stolen, the player needs to go to the roof of the Casino and dumps hazardous chemicals into a ventilation unit. After this is done and the van is delivered to the Arcade, the mission is complete. The player also gets to keep the Hazardous Jerry Can used in the prep, but the liquid does nothing in Freemode.

“
It's fate, that van is loaded with chemicals. Head over to the casino and take 'em up to the roof.
”
— After stealing the van.
“
Almost there, find the broken vent and dump all that poisonous goo. By the time it burns its way through the system, we'll be ready to roll. Then bring back the van to Planning when you're done.
”
— After arriving at the Casino.
