quazz.........My buddy has a simular roll up tonneau
on his rig. The cover is made of aluminum with
black vinal over it. He sez it works well and holds
up to NY snow and is pleased with it. I forget
what brand it is. He paid like $500 bucks for it !
It locks too as he carries his tools with him.
Me I have the $150 vinal cheapo one its ok too
