I used B Quiet in my ‘87 Westy years ago and used too much; you only need a piece in the center of a panel and not cover every square inch. For example, a 2x2 foot piece on the slider. Might not make as big a difference in a Westy because of the roof construction but Samba threads have some instrumented results if you search. Good luck ‘cause it’s a chore stripping the interior to install.
