Looking good and your flying along, should be done in time for the big melt.
Where in AB are you, I'm up in Grande Prairie
I've got two small vintage crank open windows that would work great in your doors, heres one I had in my back door that has now been changed out


I also have a Progressive dynamics converter
800 watt inverter
In Wall RV DVD Stereo
Down at the shop we also have a few windows but me thinks they would be too big for your build
Let me know what else your looking for, I may be able to help
