what are the main differences between the savage and the mammoth that make the savage so much more durable. does it have to do with the twinplate chasis? I think, im not sure about this, but the savage is the only truck that has 2 side plates that things connect to instead of the one bottom chasis sheet metal thing. is this why it is so durable? i always hear about people droping these things off 2 story buildings and nothing happening to them, why is this?
