We\'re \"fair weather\" campers, not intending to spend much time where it\'s very cold. We decided to experiment with a smaller tank. This 5 gal. aluminum-horizontal can be removed in about 5 minutes, and for me it\'s easy to put it in the back of my car and have it re-filled at the local U-Haul on my way home from work. The change made some nice extra storage space available, and the light seems like a nice touch.
