The gauge in the permanently mounted RV tank is a level gauge that detects the actual level with a float. Not the same and the pressure gauge is very mis-leading.
The flow from a RV tank could be higher than from a Grille tank, I would doubt this will work and will most likely shutoff when two or more gas appliances are fired up. Literature says 75,00 BTU/Hr max flow and most RV furnaces are 25-35K BTU/Hr. to start with.
Most important: When sometime claims: UL Listed and Approved that means that UL has a list of acceptable applications and locations for the use of a product. From what I see it CAN be used on portable tanks (such as grilles and 2nd loose tanks for a RV or Grille) but possibly MAY NOT be listed for use on motor vehicle's.
We see comments on many forums all the time about the proper use of parts and changes to and then a reference to a regulatory body. These regulatory bodies existing for a very good reason.
See: https://gasstopusa.com/ for lots of good reading.
Digging into the USA website, it does claim that it meets "applicable standards are UL 119 and UL 2061" but looking up what I can find on these standards there is a reference to 'Standard on Recreational Vehicles, NFPA 1192' but this is the overall standard for all RV's with subsections on each use or class of RV. Don't have a copy so can't tell if it is OK.
That said, unless this device is rated for use on "permanently mounted RV tanks on motor vehicle's" I would NOT even consider it. It is redundant to the existing regulator / Excess Flow Valve already installed and another component to contend with.
I would consider this for use with my grille where I tap into the RV lines for supply. In case of the grille hose leaking looks like a good product, if expensive. And for loose mounted tanks on trailers and as 2nd tanks.

This is from the FAQ section.
Does the gauge read the exact level of gas in the gas cylinder?
No, it reads the pressure of the gas under load/usage. It therefore gives a meaningful readout of gas supplies during the consumption of gas (at phase equilibrium). See the question “Is the pressure gauge useful?” for more information.
Is the pressure gauge useful?
The gas pressure gauge is a very useful, multipurpose tool.
The gauge indicates when the gas cylinder is almost empty (a decline in the vapour pressure curve). The gauge does not indicate the exact amount of propane left in the cylinder.
A steady pressure reading only indicates that propane is left in the cylinder.
If the needle is pointing to:
– HIGH: Increased gas pressure
– GAS: Sufficient gas (steady pressure)
– LOW: Almost empty (approximately 30 minutes left of gas use)
As GasStop is directly installed into the cylinder there are a few variables that can affect unregulated pressure, namely: temperature, amount of liquified gas vs rate of vaporisation, gas type and gas purity. There may also be other irregularities which affect the pressure reading.
As per the instructions, it is advised to run the gas for a small period of time to have a better indication of gas level. This allows the propane/pressure to reach something called “phase equilibrium”. Further to this point there is a “vapour pressure curve”, this is why it is recommended to run the bottle for a short while to allow for this process.
NB the gauge is also useful to represent the following:
Visual evidence of pressure decay (a minor leak) in a lock-up pressure test scenario.
Visual evidence of high pressure
Visual evidence of a shut-off
Visual evidence of an activated and stable system
Visual evidence of variable/unstable pressure
And last. Their safety compliances.
