So very sorry you are having to mess with this issue! After one year of hearing my Lippert level system "snap-crackle-pop".... With the slides in and the rear-ward landing legs up, this will put most of the fluid in your hydraulic reservoir, syphon out one gallon of the cheap fluid they put in and replace it with ATF. I use Valvoline. And in the last four years of full timing nary a peep. I replaced another gallon again just last month (two year intervals).
