Here's a good one for everyone to chew on... I have a Range Rover that I'd like to install a dual band mobile rig in.  Here's the problem: The body panels - including the roof - are aluminum.  Could it be easy to rip an NMO mount out of if I were in a garage or smacked a tree?  It's a tall vehicle anyways and it's been raised a couple of inches.  It does see mud, snow & dirt.
