I would like to know
(my dealer was not sure ,but thinks they are hollow based on the aluminum side rails of a cheaper model)
But I really would like to know for sure.
SO. anyone who owns 3.7 or 3.7i with the aluminum side rails..
Are those rails hollow? or solid?
Can you tell? (they may have end caps. If the do there would be a seam or a crevice)
Are the end rails solid or hollow?
