How about a sticky/thread in Conversion and Tutorials or Conversion General Discussions devoted to the topic "Insulation"?
There are 4 threads with the word "insulation" in the title contained in the Conversation and Tutorials forum and 48 threads in the Conversion General Discussions forum. Perhaps a creative administrator could join several of the insulation threads found on this forum into ONE thread.
Insulation is common to almost every type of RV. Having information on the many types and installation techniques in one spot would make it easier for folks to find and use.
