Definatley crate train him! He won't be able to chew anything and will be comfortable. You can come home worry free. About the SUV problem, don't open the window when he is in the car with you. Luckily this incedient wasn't fatal but it can be. Or get him a car harness or just put him in a crate in the back of the car. When he is in the SUV DON'T leave him unrestrianed. I don't really know about the bed thing sorry.
