When and where to fill onboard propane
With our class B we have onboard propane instead of removable cylinders and need info on when and where to get it filled. Can you get it filled no matter how much you have left, or does it need to...

As to the 'when' part of your question, bear in mind that not all propane really is "propane". I say 'when' because in the northern areas of North America you often get a blend (in varying ratios) of propane and butane. More butane in the summer, less in the winter.
Sometimes you find nearly straight butane, this is very common in the southern US
This is why most place call it "LPG" (liquid petroleum gas) and not "propane".
This is important because the boiling point (the reason there's gas not just liquid in the tank) of butane is a LOT higher than that of propane. At anything warmer than -44 F. propane is boiling, therefore making vapour.
Butane however stops boiling at about 32 F. so if you are camping somewhere that the temp drops below freezing and you have butane in your tank, you too will be freezing, no heat, no cooking, no hot water.
The trick is to fill your tank, whenever possible, in cold season.
