You sound like a good candidate for a set of Bal stabilizing jacks. They don’t steal as much clearance in the retracted position. They would probably mount on the frame under the rear of the cabin. You might need to weld mounting brackets to the frame. You can buy feet, or just carry blocks to keep them from sinking in.
Scamp supplies them as factory equipment now.
Scamp says they are strong enough to support the trailer to change a flat tire. Not sure what capacity they’re using.
