Thanks for the reply Michael. Sorry, I was referring to the air cleaner and it is impossible for me to exchange mine without total removal of both turbo pipes which is a real chore. Thank heavens it is only necessary every 50,000. Thanks for the good advice on the rear furnace, I'll be looking into those items. As for the a/c filters, they have placed all 4 of mine inside in easy to get to locations. Each year they improve. Happy New Year and Happy traveling. Larryjavascript:emoticon(':roll:')
