With the Gold Wing and bigger trailer space is now longer such a big issue. That being said I purchased a new two burner 40,000 BTU two burner stove. Not wanting to carry all the 1 lb. bottles I started searching for a small propane tank. My search ended with one of these.
This is a 5 lb. (1.2 gallon) propane tank made by Manchester. Cost was $43.00. 8" in dia. and 12.5" tall. First thing was to have it filled up. This new tank actually took 1.5 gallons the 1st time, cost $5.13 to fill.
During my search I found a thread talking about exactly what I was looking for. How many 1 lb. bottles are in a 5 lb. 1.5 gallon tank and found this:
128 oz in a gallon
192 oz in 1.5 gallons
192 oz % 16 oz (1 pound) = 12 1 pound bottles
This was corrected by someone else who stated this:
You are using liquid ounces in place of weight. The two are not even close to being equivalent. Depending on what source you ask, propane weighs from 4.22 to 4.27 pounds per gallon, so using 4.25 makes calculations easy. A gallon of propane (128 liquid ounces) weighs 68 oz. If you want to talk in terms of volume, 1.5 gallons of propane will equal six disposable cylinders, with a very small amount left over.
4 day camping trip in a couple of weeks ( BMW 49'er rally in Mariposa, CA.) and this will be its first big test.
6 bottles or 12, 12 would be GREAT! but either one sounds just fine. Plan is to make a mount for it on top of the drawbar just in front of the trailer. No more throw away bottles and hopefully enough propane to last a week on the road.
Will check back in with results after i've used it a few times.
