If you just picked it up at the dealer the filter element should be in a drawer,still in a sealed wrapper! When they ship from Elkhart they either (AIR) or (RV anti-freeze) the water,no filter element installed. I think you will find the door with hinges on both sides containes the speaker box! F/R seems to put the water filters where they are (VERY) hard to get too! I put a big see thru filter on the outside of the trailer. Youroo!!
