I haven't installed the carpet or dynamat yet. Other projects came up first. To be honest, I'm having second thoughts about both. The dynamat can be removed later but it leaves a sticky mess that may not be removable. I'm also hesitating on carpet because I recently pulled all of the dealer-installed carpet and it was also a nasty mess. I am probably going in a new direction: rubber up front and StarBoard XL (with built-in tie down points) in the rear.
