The correct SumoSprings for your 2019 Thor Quantum KM24 motorhome (on the Sprinter chassis) are the following:
Front
500 lb - # SSF-106-40
1,000 lb - # SSF-106-47
Rear
900 lb - # SSR-338-47
1,400 lb - # SSR-338-54
I recommend going with the 1K and 1.4K kits because they will give you more support and I've never heard of someone complaining that SumoSprings have made their ride harsh so you don't have to worry about them being rated too high.
I would like to mention one other thing as well. Typically we recommend improving the suspension of an RV by upgrading the anti-sway bars because you will see the most improvement from there. In your case it would just be the rear anti-sway bar with the Roadmaster # RM-1209-131. You will still see a benefit from the SumoSprings, but it wouldn't hurt to keep this in mind as well further down the road.
