Refillable gas bottle

Before you next fill up, check what the gauge says. Ideally, weigh the bottle using bathroom scales or a digital luggage scale.
Then when it is full, read the gauge and ideally weigh the bottle again.
It would be interesting to know how the gauge readings, weights and weight of LPG added correlate to one another.
A litre of LPG weighs half a kilogram.

The dash gauge on my underslung tank is incredibly useless ,

Some time ago I thought my dash guage might be faulty, and so I clambered underneath and removed the underslung tank's protective red cover. Inside was a previously hidden factory guage, and it showed an identical reading.

So I stopped worrying, and moved onto the next problem I'd invented.

The one in my van has four green lights when full.

In winter, with the heating on 24/7 the fourth goes out after about five days.
The remaining three go out, one at a time, at about eight or nine day intervals.
Then when the last one goes out, a red light comes on. That means you need to refill within a week or so.

I'm not sure about that, because I've never actually run out of gas yet.

 

[Rumour]

I have one of each, both plumbed in. 1 x 11Kg Gaslow and 1 x 6Kg Calor.
The Calor is there for a backup should I run out of the Gaslow - which I never have.
If I did, then use the Calor and switch back to Gaslow once refilled, BUT ... if I had to make extensive use of the Calor before I was able to refill the Gaslow, rather than just swapping the Calor out, I would just use the remainder of the Calor Gas until it was empty before replacing it, in the knowledge that I can switch BACK to the Gaslow when I needed to.
I did it this way once when I happened to have a part-full bottle of Calor, so used that instead of the Gaslow and then put in a full Calor (or Flogas - can't recall which) back in.

As far as "If you have refillable cylinders, you can top them up wherever and wherever you are", it depends where you are. sometimes there is no handy place to top them up.

But why? You have never used the Calor, so you must fill the Gaslow before it runs out. The Calor is just extra weight. But we are all different.

Ours has the same light system and works the same. We are currently in France sitting on three green lights. We last filled in April and since then have done three five day steam fairs, ten days in France in early June and 11 days so far in France. We have three greens.

But we use diesel heating which we have found to be very economical. As an average over the miles since we had in installed, we have dropped under 1 mpg over 9000 miles. Someone posted back there somewhere that it was more expensive than gas, not my experience at all. But I guess it is a hidden cost.

There are few places where I go that I can fill with LPG. I am not bothered about the weight and like the peace of mind, same as I will fill the water tank before I set off rather than doing so when I arrive.
Hassle free touring.

Yes, one fill generally lasts us several months in summer, unless we have to run the LPG-powered generator to power the aircon (which is very rare).

I can't see the point of a diesel heater if you have a tank. They are less efficient than a gas heater, noisier and use quite a lot of 12v power. And although they tun up and down to keep a temperature, they don't turn off.

They are slightly more expensive to run as well
Diesel is around 14p per KWh at £1.40/l
LPG is 10.3p per KWh at 80p/l

That's bad luck ... two gauges with the same fault
