Replacing the LP systems

The original LP gas tank was a custom horizonal tank. Based on my review, this would not be recertified. Original date was 1982 and the rust appeared deep into the steel. Couldn’t find a replacement bottle so I had to come up with a plan B. In the locker, I could fit an upright 5LB bottle. Down from the original 10lb but we are weekend sailors and this should meet our needs.
