Heist Prep: Maintenance Gear Part 1

"Of all the cons, I'm most confident of you pulling off "Maintenance worker". It's in your "range". Plus, people panic when things break down and... they'll just be pleased to see you. We need to be careful about this leading back to us, so... you're gonna steal the equipment and outfits off a legit crew. I've sent a location. Grab the bags of gear and get back."

- Lester's briefing.

Maintenance Gear Part 1 is a prep mission featured in Grand Theft Auto Online as part of the The Diamond Casino Heist update. It is a freeroam mission needed to progress The Diamond Casino Heist. Completing this setup and its second part, Maintenance Gear Part 2, allows players to use the LSDWP maintenance worker entrance disguise in the The Big Con approach.

Overview
Lester informs the player that in order for this to not lead back to them, they need to steal the equipment and outfits from another heist crew, so the player must head to this other crew's location, which can be located in places such as North Chumash or LSIA. Once there, they must search for two duffel bags with the supplies inside, but they must be careful, as the workers around them can become hostile. Once both duffel bags are delivered to the Arcade, the mission is complete.
