How long will LP last for fridge cooling?

With this added info, do you think I'm in good shape to leave it for 2 weeks without our food being destroyed, so long as the LPG is full and the solar panels are clean?

Yep !

Once that battery goes below 9-10 volts, the fridge's control board will display a "check" light (if a Dometic) and stop any boiler processes. Older refrigerators were propane only, so could just run for months on a twin set of tanks. Newer ones are limited by the battery... and at most, you have about a few days to a week before it stops. If one had a beefier bank (~500-1000 ampere-hours), two weeks might be doable.

Of course, a solar charging system makes this a completely different ball-game. A good amount of panels, a MPPT charger, and two six volt golf cart batteries would be able to keep the fridge running almost indefinitely. It likely won't be good enough to handle a furnace's amp draw after a few days, but for the fridge and the propane/CO/fire alarms, it should be fine.

Thanks for the reassurance everyone. I'm confident at this point to leave it without worry. Thanks again. All my best.

IMO;
You should be just fine propane will not be an issue and the chance of the burner not working is remote, the batteries will stay up with the solar charge.

The frig uses very little propane and very little battery current.

Just have your battery checked. Should be OK. Ours sits in the yard for weeks at a time and we always have the heat and the refr on. don't keep the dord attached except when it's cold and need the heat.

And here comes the lawyers.

Where are you leaving it, your own private property or paid public storage
Guess what you could be in violation of their rules and local laws
By leaving the propane on and fridge running

Should be just fine for that length of time. I'd think several months.

Yes!
