Hey all! I'm going to build a hearthpad in the next couple of weeks. A Hearthstone Mansfield will adorn the top! So.....what do you think - use 2x4's or 2x6's? The stove sits fairly low, so was thinking that raising it 6" + the plywood, durock, tile, would be nice for loading, but....didn't want to go too high - just looking for advice. Thanks! Cheers!
