dude...the way they make things nowadays is with cross beams...

the shell is most likely hollow and thin aluminum for weight savings... but there are serious cross beams inside that aid in supporting the weight in the event of a rollover...

don't think you can stand on the roof without some section of it caving in...but i'm sure it will protect you from a good rollover...

makes you think about the roof rack and the functionality of it doesn't it???
