Where do I install Scissors Stabilizer Jacks (Peaktow) on Navion 24J 2013?

[yfor01]

2013J on Mercedes Sprinter 3500 chassis
PeakTow Stabilizer Scissors Jacks 9000 lb Capacity
DIY installation
2 on the back only (at this point)
Can anyone provide a diagram or picture of the spot I should install?

Looking to use the included mounting screws but may weld them in place!

To make life less complicated, I would not mount them permanently. Just put one at each end corner of the frame rails where the tow bar bracket meets the frame. Additional height can be gained with a couple pieces of 6x6.
