Put SafeTPlus on our Berkshire and feel it really helped firm up the steering and easier to drive.
Another thing we replaced is the outside porch light (around $65) with one with a motion activacted smart light, really nice a night when you come back to the MH and light comes on. Fits the holes and uses current wiring for the current light.
