Ccarvalho224 I bet it's a utility truck reskinned to be a lifeguard truck. I saw a pic of the guide that was floating around and it had a large utility cherry picker type truck (white) and a small 2 door pickup with a utility body on it (also white). That opens up the possibility of fire department rescue squads also since LA county I believe still runs them (like squad 51 on emergency!)
Could be. And that would be awesome to see.
Unfortunately, I think your squad theory is unlikely because, you're correct; LA County does still run paramedic squads (I loved Emergency!), but LA City does not. LA County Fire only provides lifeguarding services to the city of Los Angeles, while LAFD handles everything else in their jurisdiction including EMS. And Santa Monica (Del Perro) has its own fire department (not in the game of course).
I think all we'll have is the engine, and (I'm crossing my fingers, but anticipating the worst) hopefully a tiller truck. I mean, they brought back tractor trailers, this would be a perfect, new and unique addition to go along with the new car carriers, log trailers, tanker trucks, etc. It'd be kind of a let down if Rockstar didn't take advantage of such an opportunity. Or maybe there will be vehicle DLC? Who knows...
But we'll see when the game comes out because all these livestreamers are just doing whatever they feel like people want to see, which I'm enjoying so far. But first thing I'm doing when I get the game is calling 911 and see what shows up.
