My bathroom is less cold when I used one of those cushions for vents. Since I camp mostly with full hook ups I just plug in a little heater fan and pointed towards that area.
A good way to find out if you have a water filter is to find the location it would be and check. It's not uncommon for members to think that they have one when they don't or the opposite.
Great choice for "Living within my means" and camping for one...
