It's fairly new to us so I did alot of reading and asking.
The John deere dealer, his shop is at 7,000ft, said he has NEVER installed a high alitude kit.
The Polaris dealer, also at 7,000ft, said he'd do it if I insisted, but he's never installed one.
My ancient small block Chevy/holley didn't need it in its move from 431ft to 6,500ft, my ancient three 2 barrel car didn't need it in its move from DesMoine to 6,500ft, my propane grill nor the rv nor the three patio heaters needed it.
I asked on all of them. No one I know has installed it on any engine, gas or propane.
I did not give up on the need. I read, and reread and dug deep.
I still sorta am doing it.
If I want my 60 year old car to get .1mpg better I can rejet the carbs.
If I want my heater to get .01gallon per day better I can rejet the the gas orifice.
The
Not over 5,000ft story
is a legality of a liability issue about the fuel burning at 89% efficiency vs 91% efficiency.
Truly, undeniably, a gazillion miles of rv miles at altitude over the last almost 100 years disproves their engineer crap.
You don't really think Mrs Ima Dummadz, the worlds dumbest rv owner, rejetted or didn't run her heater? 100,000,000 road miles over 100 years of propane usage says it works just fine.
It is only a legality liability thing.
It does not harm your equipment except for some soot(if your propane is nasty)in the flue.
If you're dumb enough to use a charcoal bbq for heat in a one bedroom apartment, you'll somehow, over years and years of use, find a way for the Squirrel clogged vent propane heater to cause you discomfort.
Related but different.
The 300ft. Cat5 'limit' is 300ft because the building the original tests were done is was
300ft long
And they didn't test it further.
Punchline:engineers say stuff sometimes. Stupid stuff. Then stare blankly when confronted.
Rejet has to do with unburned fuel in the minutest amounts, nothing else.
Honest. look ut up, use your common sense when reading instead of relying on the authors to not have an agenda.
Medically, high altitude starts at 8,000ft.
Thr venturi door on a propane torch let's you adjust the air/fuel mixture.
No death, no hurt, just a different flame with a different heat.
A considerable portion of the world's population lives above 5,000ft.
I think they likely use propane(ask the company who says no. Prepare for the blank stare.)

What did you learn, or think about the 2019 Onan 5500 that comes standard with Altitude adjustment (0 - 5000 ft)?
We live 488 ft above, so generally speaking it is non issue for us. But thus far, we have had limited trips at high altitude. My general thinking is that since I don't or have enough experience, I will error on the side of precaution very any potential of damage or Mfg saying warranty is no valid because you were in an area of high altitude and did not follow their guidelines.
I can now cite my experience of running water heater and Norcold fridge at about 7,000 ft without noticing any issues. I didn't really need to try the Suburban heater. It got down to a low of 52 inside the RV at about 3:00 AM in the morning and I was wrapped in blankets
I agree that buying any aftermarkets kits is not in my future. But I will continue to adjust my Onan to the specifications and in cases that exceed what the ratings are for any of the equipment, I will opt to avoid the risk and not use unless it is just an absolute necessity.
FWIW, we had trouble with our propane grill at high altitude, but I could not tell if it was propane related or wind related? 3 times it had gone out in the middle of cooking. We never had had that issue anywhere before.
