Do you think you need them? Have you camped in it yet? Our Greyhawk had 2 slides and one of the slides had the bunk beds in it. When the kids got in and out of the bunks, the camper would rock side to side. So we bought stabilizers to help with that.
I found the stabilizers worked best at the corners of the house body, not under the frame. When I tried them under the frame, I noticed no difference. When I moved the jacks to the corners of the house body, the camper was a lot more stable. It still moved a little, especially if someone jumped off the top bunk, but it was much better.
We did not use scissors jacks for stabilizers as I wanted to buy cheap in case they didn't help. I bought a set of
these from Walmart. Since they didn't do anything under the frame, I am glad I did. I think it would be difficult to use scissor jacks at the corners of the house body.
The 24B only has 1 slide. Since the slide is on the opposite side from the entry steps, you may find your motorhome rocks a little when someone steps into or out of the motorhome. Putting scissor jacks under the frame most likely won't help with that. The rocking is caused by the Motorhome's suspension and putting jacks under the frame won't stop the suspension from moving, unless you lift the Motorhome off the tires, which is not advisable. With the jacks at the corners of the house body, the suspension is no longer an issue.
