I'm trying to confirm now, which brought me to this posting.
The service writer is absolutely 100% incorrect / wrong.
I actually have the very same trailer - 2017 international serenity 30RB - and the stock dometic AC units only had traditional start capacitors installed.
Some people believe that a start capacitor performs a “soft start” function. To a certain degree that is true However a simple start capacitor has limited energy storage / ability to dramatically reduce amperage demand on startup. It really cannot be compared to a software controlled smart start device like those I cited in the previous post. (Btw - each of those devices actually have a start capacitor included in the housing - the difference being that current is carefully controlled by a processing board with embedded software)
I personally removed the $20 start capacitors in my 2017 and replaced with 2 MicroAir Easy start software-controlled soft start units in both the forward 15k unit and bedroom 13.5k unit.
They work as advertised and dramatically reduced amperage draw on startup.
