The hyd. pump and resevoir should be located in one of your outside compartments.
The resevoir is rectanguler shaped with a fairly large hexagon shaped bolt that is threaded into the top of the resevoir. When this is removed there is a dipstick on the end that shows hi-low marks.
Always check the fluid with your slides in and your jacks up.
If you have trouble finding it, walk outside, open some compartment doors and have someone operate the slides or jacks, you should be able to hear its location.
