since all my money is tied up in wheels&tires and that doesnt invlove doing anything over than buying them. i want to weld up a a full lengh roof rack and im goning to use half inch steel. i was just wondering if it would be too heavy..is there a crush weight for the roof...a while back a saw a funny picure of some guys roof caved in because he put to much plywood on his roof...and i dont want to load up the roof with crap on long trips and worrying about the freakin roof caving in...on the plus side if there is nothing to worry about it would be cool as all hell to throw a mattress up there to sleep on long trips.. just would not want to roll out of bed
