Keith,
I did see a tank underneath the step but didn't know what it is for so thanks for the info. This is our first coach so we have lots to learn. Do you know anything about the windshield wipers? We took off for a short trip and it started to rain and the wipers were useless. We stopped at camping world and bought new blades. The passenger side is working great now however the driver side seems to miss the window. Doesn't seem to be enough tension on the arm. Haven't had a chance to get up there and take a closer look yet. Thanks, Larry
