Unless you are driving for more than 5 or 6 hours the fridge will stay cold without being turned on.
I don't run mine when driving because we usually don't go more than about 3 to 4 hours at a time. The fridge is always still cold when we stop. That's just my routine.
What are you basing this on?
Actual temp measurements?
Items 'feel' cold?
Freezer stuff still frozen?
Measure temps with a thermometer that will show/record highest temp reached and you will be surprised by actual temp reached in very short time in 'food section' of a perfectly closed/unopened rv fridge.
They just do not have the thick wall, high insulation factor....are exposed to ambient temps via outside compartment/drip tray drain hose and inside temp of RV.
Food spoilage (bacteria growth) when temps go above 40*F.
OP.......
Propane failing to ignite at higher altitudes is due to the thinner air. Air/fuel ratio becomes 'fuel rich' and is harder to ignite.
Neither Norcold, Dometic or Atwood have a 'high altitude kit' Suburban does have one for their water heaters (different size orifice *smaller* which has to be changed going above/coming below 5500')
You can try:
Removing lower vent/access panel when stationary
ID which size orifice you have and try one size smaller (swapping back/forth)
Provided you have already checked that spark gap is correct and in position, Checked that burner is clear propane flows freely
