finally got the shimmed bytal tape so it was time to attack the vista views...

 dismataling was easy just remove the snap ring with some needle nose plyers then I used a heat gun to soften the old bytlal tape then with some gentle pressure from the outside the two layers just fell inward (make sure you have someone inside to catch them!!)

Cleaning them and keeping them clean during reinstallation was the hardest part of the process.

 you also have to clean  the frames

Applying the new tape to the plexi pane

  the windows back in place and a nice patch of sky!

The back side of the camper has no leaks so I have started insulating with an air gap then foil insulation then 3/4 ridged foam 

 My rosie the riveters

 Piecing in the ridged foam not the easiest place to get in to fit.

 Some additional help from the Ginkster.
