Hey Jason, thanks for getting in touch. For a Dometic AC unit I recommend the SoftStartRV Soft Start for Single Zone Air Conditioner Setup # SSR54FR. This is a universal soft start, and it is known to work with the Dometic units.

The chart below shows an example of the results you can expect.

Your camper is a single zone? Or do you have more than one AC unit running off the same controller?

Hey Jason, did you end up trying the SoftStartRV soft start with your Dometic AC? I'm curious if it worked well with your camper’s setup. Your update could make it easier for others choosing a soft start for their Dometic unit.

@JasonU Dang I am sorry to hear that. Those Soft Starts come with a 2-year warranty. Did you end up doing a warranty claim and getting it replaced?
