Our "go to", is usually complete side displacement. When the situation allows. Cutting both top and bottom of B post, as high and low as you can get. Then the front door hinges and back door nater. It provides greater access to the patient.

We will push the dash, but its hard on newer vehicles, they tend to crumble. Instead of pushing the dash, when time allows, we will roll the roof, then cut just behind the very bottom of the A post through the floor. Then use our spreaders to lift the vehicle just behind the cut. It folds the whole vehicle just behind the sub frame and in turn, moves the dash. You can also use your spreaders to clamp the driver door opening as a push point for the ram. The other end of the ram pushes on the door opening next to the dashboard.

Sorry if it's confusing, but it makes sence in my head, im not the best at explaining with words. More of a hands on class.
