Whatever happened to fiberglass LP tanks ?

It seems like you would care "exactly" about the level in your final/last in-service tank.

I watch the level in our single 60 lb. (18 gallon) tank carefully, as we camp out West a lot and are not always only a hop-skip-and-a jump away from propane ... if I even know where propane sources are at any particular time.

We also like to think of our RV as a smaller but portable extension of our brick and mortar house ... so we keep our RV coach's interior temperature no less than 60 degrees at night - the same as our house.

Those two requirements mean that I need to know what's going on with our propane level at all times - otherwise we'd have to run the generator almost 24/7 to keep the refrigerator cold and the RV warm until we could find propane somewhere.

The OP may be similar in their camping situations and desires.

A friend of mine carries a $10 bathroom scale and a small square of plywood for a flat platform to sit it on. On his TT, he's able to lift up the in service cylinder enough to slip the scale and plywood underneath it and read the weight. Subtracting the tare weight tells him exactly how much LP is left. I've also seen someone use a hanging fish type scale to weigh a cylinder.

Answer - I don't care. I installed that propane tank cover viewing port because I could, not because I had to. :W

99% have auto switch over regulators, start with two full tanks, both open.

Downside is that with both tanks open you can easily drain both and be left with nothing, especially when the tanks live under a cover that hides the auto changeover regulator's gauge. :M

Well I would figure how to put a sight window in the cover.

As I've recently done as one of my winter projects. :)



Not much to "figure out" ... just cut a hole in the appropriate location and secure a piece of clear plastic over the hole = done. :B

i.e. Suppose you what to boondock camp out in the middle of nowhere many miles from where propane is? Whether you have one, two or more tanks and no matter how they're hooked up you still might want to know absolutely how much propane you have left near the end so that you can plan the next long trip to refill - especially if you get hit unexpectedly with a run of cold weather out there boondocking.

These fiberglass ones are not as used in RV's as much as the boating world. Boats do not have the same carry capacity as RV's etc. So Aluminum or fiberglass are used more. Along with in salt water conditions, the steel ones rust much quicker than on/in a land yacht.
If you race a sailboat as I do, you count how many lbs you can leave behind. so the lighter cylinders are worth it to a degree.
They do command a pretty penny tho.

I wondered about these. They had some cool advantages, mainly the ability to check level, and being lightweight. However, I think the entire market for fiberglass composite cylinders was killed by the company that went under, as people thought all composite cylinders were flawed. Even with good ones like Viking, it may be tough to get them filled.

As for what I do, I have three. Two are on the RV with a changeover valve, one is kept filled/exchanged and ready to go. That way, when one goes empty, I just swap the filled one, then next time I hit a Lowe's or other store, I exchange it.

We owned two of the banned fiberglass cylinders. The company was put out of business by the government as they had no quality control testing as required by law and when tested had a high failure rate. Anyone who had one lost their money because they can't be refilled and the company filed bankruptcy.

I also had two of the Lite Cylinders. Bought whwen they first came out about 12 years ago. One of the cases broke and they sent me two new ones a few years ago. Everyone kept filling them until last year. They went broke because they couldn't afford a recall after a couple failed.

Or Heinz ketchup !

.... I run the tanks sequentially - open one and use it 'til it's empty, then manually switch over to the second full tank. At some point later, at my convenience I'll get that empty tank refilled, then repeat the cycle once the second tank itself has emptied. This way I truly don't care about monitoring tank levels.

X2, same as Mayo, one in fridge, one in pantry. When one is emptied, use the other, and put it on the list for grocery shopping! Never be without! :B
