Yup. I have seen that video awhile back.
And it all makes perfect sense!
The only obvious difference ofcourse is that in the video he is applying to wrapped sheathing, and I dont have that.

SO I will be installing my nailing flange directly to the exterior T1-11 on my house.....caulking,...using a narrower band of tape...since I cant use 6-8" tape.
Then putting up the trim,....cauling the hell out of that.....and mabe a nice little z at the top.
Now worries,.....

Default sounds good

Sounds like you have a handle on it.
For the top piece of Z flash, make sure this is done as best you can...this is the most important area after all.
Good luck.

What is the reason nobody suggested (assuming there was no sheathing under the T1-11) nailing and flashing the window to the studs, then installing the T1-11 over the flashing? Frame goes on over the T1-11. This is the method I've used. T1-11 without sheathing (directly over builders paper or housewrap) is common, since it's rated for that even in hurricane-prone areas.

I would pull off the one sheet of siding, pull the studs that are in the way. install header, king studs, jacks and criples. Opening should window plus 1/2" repair house wrap install window and flash it. Make a nice cut out in the sheeting and re-install.
