The 6 point Level-Up system is not supposed to tie into the hydraulic slide outs according to the
aftermarket manual (last page) but they do. Apparently the slide out rams get their retract pressure from the L and R jacks! I replaced two hoses (orange and black) from the middle right side jack to the right rear jack. Tested them and the jacks worked great L and R. Tested slideouts they extended but would not retract. Apparently the slide out rams are the last devices on the daisy chained retract jack circuit, L and R.
