Bought this about 3 weeks ago but just got around to building it.  Instruction need more information about where the extra holes on each board should be facing.  Had to run to Lowe's and buy more 2 1/4" screws to attach the roof.  Called for 14 screws and we only had 4.  The t nuts often stripped out.  My wife and I built it and it took up 27.5 hours.
