Alternate LP gas storage methods

[Aage]

Here's an unusual way to carry LP gas with you. Have a look at the photos of this trailer in the Classifieds:

I wonder what his tongue weight is?

Interesting. Looks like about a 100lb tank. Shouldn't be all that much more than two 40s. You'd save some weight being a single tank instead of two smaller ones.

If you're comparing like materials that's probably true, but I think a steel 100lb tank might weigh quite a bit more than 2 aluminum 40s. A steel ASME horizontal tank for 23.4 gallons of propane (roughly a 100# tank) weighs 108 lb empty. My 30# aluminum Worthingtons weight about 18 lb each, I think a 40# Worthington is about 20 lb. empty.

You're right, I was thinking about steel tanks. I can check when I get home and see what my steel 40# tanks weigh empty.

I just checked, my two steel tanks weigh 30.4 lbs each.

According to the Worthington chart at VTS, their 40 lb aluminum tanks weigh 20.9 lbs each. Good guesstimating DKB_STAX!

Interesting that the large tank weighs so much more. Must be made of much heaver gauge steel to handle the larger capacity.

Interesting trailer...It is a 1977 but has triple axles and is listed at 34.' Has this been tinkered with and extended by a prior owner or is it an Airstream factory one off from 1977? The frame size (the hitch area picture shows it) is definitely not stock 34' frame material. I would be a bit concerned about enough frame for that much lenghth.

The difference is, for the horozontal tank, the mounting devices are part of the tank; for the upright bottles, the mounting devices are part of the trailer. Add the weight of your propane bottle brackets (not including the cover), and the weights will come out closer to the same for the same capacity steel tanks.

Having portable aluminum tanks makes it easier to get a refill without moving the trailer. It makes it easier for camping for longer periods in one spot. Just take the tanks somewhere to get them filled. Portable tanks offer better flexibility for your flexible trailer life style.
