No gas to cook top
Kids are camped at Canyonlands NP at 5400 feet. New Escape RV. Gas to all other appliances except Dometic two burner cook top. It was working just a day ago at lower elevation. Is altitude really ...

What I am stating below, is from my background in industrial pressure controls in gaseous pressures (N2, Air etc), steam, and water. I a not a certified LP gas tech, but this is what I have found on RV systems I restore.
The main tank regulator normally has a 11" WC setpoint with no load. There is also regulator droop when an appliances kicks on. There may be a slight dip, then rise above 11 " WC. It should not exceed 14" WC when appliances are on, like the furnace and other large or small volume appliances. With the quality of standard RV gas regulators, (throw away devices, not repairable) it is getting harder to find a new one to hold between 11" WC and 12" WC when running. This may be considered normal in the RV world, again the 14" WC high limit.
Also, there is a tolerance on this, your 10.8" WC and 10.9" WC is an 11" WC in the eyes of many gas gauges with dial increments of 1" WC". In order to read 0.1" WC and be considered accurate, and traceable to the NIST (National Institute of of Standards) you need to buy a very expensive calibrated meter in a calibration program. And then there is how "accurate" +/- the meter is from it's reading.
Trying to dial in a RV gas regulator from 10.8 or 10.9 to 11.0" WC and the regulator be repeatable, is not practical from what I have found. The RV main tank gas regulators in general, again from what I have found, are rated in whole numbers for setpoint of 11" WC. There are not listing decimal points. If someone knows of a quality RV brand gas regulator rated in 0.1 decimal places that is repeatable to those decimal places, please let us know.
Hope this helps
