You're making progress and following the plan; keep it up!
How old is the garage? The reason I asked is because in one pic showing one of the beams, it looked like the ceiling had some water damage in the past. What's the condition of your roof; hope it's not as bad as your neighbors. lol Speaking of the neighbor's roof, it made me think your garage is built on quite an up-slope to be looking down on his roof. Your insulation work is going to pay big dividends come winter; any idea how much (if any) insulation you have in the overhead? The POD is a great idea for storage, and a great motivator (@ $400/mo.) to get the garage done and move things back in. Good luck and keep us posted on your progress; looks to be a great transformation!
