Travel Trailers have to use external generators and if a properly sized one is used the A/C runs fine. It's only when you have a limited power generator that you would need/want a soft start kit. RV A/C manufacturers build their units assuming the RV will be connected to a power supply of sufficient capacity. They do not engineer/build the A/Cs to operate with marginal power that will cause an early demise to their product.
Most camping here isnít motorhomes.

If you don't have a generator why would you need it?

Do you think the A/C manufacturers are going to make "Western US" versions and "Eastern US" versions?

And again: why would A/C manufactures engineer/build the A/Cs to operate with marginal power that will cause an early demise to their product. They build them to be run by power supplies of sufficient capability. It's not their intent for the end user to try to get by on a minimum sized generator.

To meet customer needs. $10 is less than $1,000 for an additional 1000 w generator.

Yes, manufactures often offer regional variations; e.g. CA pollution controls.

Time will tell if they wake up to the opportunity.

The closest we come to dry camping is at racetrack. We usually pull in on Friday night and spend night to race next morning. It beats getting up early to drive 60 to 100 miles then race. The 4000 installed in Vegas runs 15k a/c no issue. I have a Champion RV ready 3500 starting watt generator on racecar trailer. It struggles to start 15k a/c. The bigger capacitor may make it easier.

I do this as the purchase/operating expense is low on Champion, $316 delivered and it runs 9 to 16 hours on 3.5 gallons of gas. The RV generator has 485 hours on it, the champion is at least 10 times that. We have been to multi day races where I stop in morning and late in evening to check oil and fill up seemingly days on end. It is 9th starter cord even though it rearly takes more than 2 pulls to start.

I will order the cheaper of the 2 options and try it.

I use the Supco soft start on HOME air conditioners. For 10 bucks, you can't beat it. When a unit gets older, parts start to wear and the unit grabs a little more power to start up. You plug this in parallel with the original capacitor and you're done. If you can find the capacitor on an RV unit, the principal is the same.

The purpose of a hard start or soft start is NOT for you to get by using a small generator. It for running an A/C on a low voltage shore power system to prevent damage.

I started the thread so I thought I should clarify: I also emailed Dometic to clarify whether adding the Supco would invalidate my warranty. They responded that the Penguin II model I have already has a soft start capacitor from the factory, so I'd be gaining nothing. Perhaps this is something manufacturers are starting to do, so check your model before installing.

Just for clarification, the $10-$15 Supco unit is called a Hard Capacitor. Soft Start is an entirely different thing and very much more costly.

All A/C compressors
have a start capacitor. Home or RV. A hard start cap is for an aging compressor or a low voltage condition. You don't add a hard start. You change out the original cap and install the hard start. it's just a start cap with a bigger kick. No such thing as a soft start capacitor. That is another Made up phrase in the RV world started by newbies. Soft Start is a trade mark unit made to help with low voltage conditions and/or borderline amperage availability.
It has lots of electronic parts inside. No need to add one just for a properly designed RV generator system.

Big start capacitor vs ramp up soft start are two different things. I just watched the Micro Aire Easy start. Is impressive. 41 amps down to 17 on 15k btu RV unit. I will order as even the Champion 3500 struggles to start. Not cheap, but considering wear and tear on both A/C, generator and wiring, is worthwhile in my application. It will likely quiet unit startup to degree as well.
