2017 Thor Compass a/c works on generator but not 30 amp

[Major_Dad]

We downsized from a 34' TT to this little MH due to my disability, and to make travel easier. The 13.5 a/c works great on the propane generator, but shuts down when the compressor tries to kick in. The manual says nothing about this. A trusted technician tested the power outlet on the house and the 30 amp cord, and the problem isn't there. Anybody have an idea what I'm missing?

Good question...but no breakers trip. The compressor tries to start, then shuts down. If you try to start it again, the same thing happens. The blower isn't affected.
