replacing rear scissor jacks

[kansas49er]

Greetings. We own a 2004 Fleetwood Wilderness 250RKS Travel Trailer.
It is quite low to the ground, and if we go thru much of a road dip, one or both rear scissor jacks rub the ground. I have replaced one (left side) once already, and need to replace it again, as it bent on impact with a deep dip in the road. I am wondering if there is something else that I could use, like perhaps some sort of jackstand that was removable when towing down the road. Any ideas? Anyone?

Thanks so much for your consideration in answering.

Is there enough room to bolt something like this to the side of the frame?

First thing that comes to my mind is, can you mount them closer to the rear axle? Do they have to be way out there where they can be damaged?
