Hey James! You can use the Soft Start Kit for Coleman-Mach RV Air Conditioners # CM56RR with your Coleman Mach 10. It will work with your newer 35000 series in addition to the other ones listed on the product page.
What kind of trailer do you have and where do you typically camp?

I put the recommended CM soft start on my 22' trailer that had a 15k AC on top. It tripped the gfci on a 15 amp c12ov circuit, but works fine on a 20 amp and also with my Honda 2200 generator. Great move I think.

I installed the kit on my series 4000 Coleman Mach AC in my Grand Design Reflection 5w. To test it out, I unplugged from shore power and used my little Honda 2000i generator as power.The AC powered up and ran easily with hardly a noticeable added load on the generator. Ran it for about 20 minutes more without issue. This kit ROCKS!
