I am considering purchasing an H1 in the future, probably a wagon since it seems they offer the best cargo space usage for "work". but one of my dislikes is how the entire rear is carpeted. I have been wondering and searching the 'net for somebody that may have ripped out the carpet and lined the cargo area, including wells, either with spray on or DIY liner. I know you have a humvee but its the closest i've found. How dis it turn out for you? Did it make it louder? The noise is my biggest concern.
