Question:

I have a 100lb cylinder that I would like to hook to my rv. Which regulator and what size hose would I need to use. The distance to the trailer is 15 feet.

Your travel trailer likely has a regulator with an automatic change over valve built into it. As you probably know, when the first bottle is empty it switches over to the second bottle. The bottle and switch are before the regulator, so only the one regulator is required.

I suggest that you replace the very short pigtail hose that connects one tank to the regulator with a longer hose that will connect to the 100 pound tank. In that way, you can run off of the 100 pound tank till empty and then after the change over occurs you will know you only have a little further to go.

The longest supply hose I have is the JR Products # 37207-30685 which is 12 foot long and has a POL fitting on one end to connect to your 100 pound tank, and a 1/4" male inverted flare fitting on the other end to connect to your trailer.

If your circumstance are different, just email me back with the details for an updated recommendation.
