View/Navion Profile thermal cab divider

[Schoolhouse]

Planning for cold weather camping. Last year our rig got pretty chilly. Trying to reduce the cubic feet being heated by installing some type of thermal barrier between the cab and the living space.
I have seen “On the Road with Ron”’s YouTube video for his View with the bunk over the cab. Pretty clever! Our View Profile version offers a few more angles and cabinet doors to maneuver around. Has anyone seen or heard of a solution or do we need do get creative like Ron?
Thanks in advance for any ideas.
