hello all, i am just curious, i just bought a new 2015 cruiser 362FL 5th wheel 40 ft, i always like to stay on top of things, come winter time, we always winterize ourselves, on this particular rv is there an inline filter some where in the coach? if so, can any one tell me where it is. under the kitchen cabinet, etc, i use the blue filter on the hose since i got it, but i dont want somthing to freeze when it gets to that time and i didnt dump the water out of a filter housing. thanks in advance.
