With the framing complete it was time to get some exterior sheathing/siding installed. I ended up using LP Smartside panels which can be found at Home Depot. This is a pre-primed engineered wood product which basically means it's a lot like osb with an overlay that give it the faux wood look. I chose it over plywood T1-11 because I've seen issues with T1-11 swelling at the bottom of sheds. I also chose it over Hardipanel because I was doing all the construction work alone and just the thought of muscling around 4x8 sheets of Hardipanel by myself gave me a hernia. Each panel has ship-lap edges so installation was very simple. I believe it took a total of 10 sheets.
More pictures of the sheathing on the doors and cutting the vent openings can be found in the "Doors" and "Vents" sections.
