I am not sure if this has been suggest or not,
I've been around a few different Regions in the US. Some of the Ladder trucks have some light rescue capabilities (I.e. Jaws of life Equipment). I was curious if anyone has suggest MVA's have a ladder attached to it for some of the mission to have a quick extraction of a victim from a vehicle, with the possibility of it upgrading it for a HR to come on scene for a complete vehicle stabilization because it over a cliff.
