The comms from Truck 1, the lead truck of the responding vehicles and thus the one doing the comms for all of them, I don’t like the comms used. “Truck 1 and company” is too general, and doesn’t convey specificity to the ground controller. Especially for crossing an active runway. The better way to communicate it, and the way I’ve done it before when in the lead of three vehicles, is to instead use callsign plus number of additional vehicles. So something like “Ground/tower, Crash 5 plus two, holding short of RW 4 at Delta to cross.” That tells the controller specifically how many vehicles there are in your “formation” of vehicles, and lets the local controller plan how big a gap they need to get you crossed. From then on, the formation uses the callsign of the lead vehicle, plus the number of following vehicles. If it’s just a routine crossing, non-emergency, then the controller has time to get a large gap. If it’s an emergency response, he may have to wait for a jet to land and pass the intersection, and may even need to slow the next plane on arrival, or even send it on a go around if needed.
