Hello all, has anyone used this on their rig? Thanks for the advice...

Propane automatic shut off valve

The valve built into the propane tank has an overflow shutoff, but this has a small bleed (when connected to a hose) to equalize pressure and allow the main valve to open. My understanding (and I don't have first hand experience) is that the device you are considering will shut off this small equalizing bleed.
When there is nothing connected to the tank, the internal valve shuts off all flow, even if the manual valve is opened.
The "gauge" is of limited value because it is measuring vapour pressure rather than liquid level. It will wander around in the green zone depending on ambient temperature until the tank is almost empty, all liquid propane has evaporated inside the tank and vapour pressure begins to drop.

There is an excess flow valve, the 'leaky' check valve, in the hose fitting that screws onto the cylinder valve Acme thread outlet. As long as there is excess flow, this valve limits the flow of propane to minimize a fire hazard. It also comes into play when the downstream hose is empty or near empty and the cylinder valve is opened quickly. The built-in leaky bypass limits flow until the pressure is balanced across that valve and it then fully opens.Ted

Question: will the GasStop work with an excess leak valve pigtail? GasStop defines macro leak for it to work is 70 cfh(cubic feet per hour). The pigtail excess flow valve bypass flow is about 10 cfh. Will the GasStop respond?Ted

I bought two of these earlier this year for my trailer. After my second trip this year with them installed, I have taken them off and will not use them again. The major issue is that it will shut off the supply if the road is rough enough. Unfortunately, on both trips, on major highways, the valve has shut off the propane supply at some point, which is not good if one is carrying medication that requires the fridge to work, although I doubt it would warm up enough to affect it, not worth it to me. The accuracy of the gauge is no better than the knuckle knocking is, or lifting the bottles to feel the weight. Two Mopeka sensors now ordered to replace the GasStop.2021 GD Momentum 320G 8K Axle

Thanks guys, I knew there was some kind of safety valve on the tank, just didn't know how it worked, and was taken in on these valves. As they say, live and learn. I do now have them for sale to anyone..lol.2021 GD Momentum 320G 8K Axle

There's an Excess Flow device built into the pigtail . This safety device is on all of our trailers since (presumably) all of us use propane cylinders not tanks. (Tanks are used in motorhomes.) The pigtail is the hose that connects the cylinder to the regulator.

Note in the text explaining how the device works that it will allow a small amount of propane vapor to bypass. The GasStop device is supposed to shut off even the smallest of leaks. Chad from Changing Lanes did a video on the device about 4 years ago. If you haven't seen it, check out https://www.youtube.com/watch?v=nITU1SWow2k
FYI, I have no opinion on the device one way or another.
ADDITIONAL INFO
What's inside the cylinder (often mistakenly called a "tank") is a safety device with the name Overfilling Prevention Device.
