We do have the correct SumoSprings suspension enhancement for your 2015 Thor ACE 30.1 motorhome, though not both part numbers you mentioned will fit. The front and rear SumoSprings that fit your Thor are:

- Front Axle: SumoSprings Rebel Custom Helper Springs # SSF-170-40-2

- Rear Axle: SumoSprings Maxim Custom Helper Springs # SSR-187-40-1

These springs are going to do a really good job of helping you maintain control of your rig and reduce the back-and-forth sway that can make handling your motorhome a chore. I have added links to video reviews of both parts for you to check out as well.

The SumoSprings Rear # SSF-170-40-2 and Front # SSR-187-40-1 mentioned above will also work perfectly on your Thor Ace 29.3. We don't have any specific recommendations from an installer in California, but any local trailer or RV dealer/shop will be able to handle it without issue.
