I can't take credit for this mod, so I'll share the link to it:

I just got back from the camper, and it was a success. I'm anxious to see how it affects the heat/cold transfer from the cab to the coach; hopefully it can add some benefit.
I will say right off the bat that setting camp up will be easier. I hated fighting w/ that cheap windshield curtain that my rig came with. Now its just put the Heatshields on the glass, and draw the drapes closed.
Only downside I see is the parachute cord now runs across the opening even when we're driving. DW will need to get in the habit of ducking as she moves about the cabin while we're underway.
