Your Gas Bottle(s)
?Tell it what you've got and how full it is. If you're not sure, a servo or swap-a-bottle point can weigh it for you.
If you're not sure how full a bottle is, most servos and swap-a-bottle points can weigh it for you — the tare (empty) weight is usually stamped on the collar.
What's Running on Gas
?Add everything drawing from your bottle — pick from common RV appliances or add your own. Adjust the MJ/h if your appliance's rating differs.
MJ/h figures are typical published ratings, not exact — check your appliance's data plate (usually near the gas connection) and adjust here if it differs.
Your Result
?Updates live as you type. The bottle colour reflects your estimated days remaining, not just how full it is — plenty of gas but heavy usage still turns it amber or red.
