Got the door put on and got the painting out of the way!
I added 2x3 on the door to straighten out plywood, and it fits right inside the cab when door closes with a 1/8” gap all around. I will put that weather foam stripping along the inside so when the door closes it makes a seal along those 2x3’s, with a second set of stripping along the face of the cab where the plywood of the door touches when closed. Should get a full seal with 2 barriers.
Along with the hole drilled in bottom of cab for intake I got the hole drilled through the wall of the shed for the out take.
