W2 Mopar inspection w/RAMM

"Uhhhhh, no the W5 is NOT an aluminum W2. Not even close. Neither is a W7 which isn’t a W5."

I think it was just a tongue-in-cheek comment...but telling nonetheless. I bought W7's specifically to avoid the tales of leak issues with W5's. For what it's worth, I've been told the W7/8/9 are all very similar and are sort of in a family by themselves. The W7's that I have look like W9's with a lot less material removed (or cast).
