Here is a texture of FDNY Engine 238, Ladder 106 and the Foam Tender Unit. All three units are housed in Brooklyn on Greenpoint Avenue. The Foam Tender unit is rarely used in calls, and only used in major emergencies such as a fuel spill. And normally, they use a older 1990s Mack MR, but unfortunately, I could not find a Mack foam tender for GTA 5, so I have to use what the modding community has here. Also, I know that Ladder 106 is normally a Seagrave tiller, but I could not find an accurate model for it, so again, I have to use what the modding community has.
