I am not familiar with your model, but on our 40KD, the ends of the rams are accessible from underneath the wheel well for the front on the passenger side, and from inside the lower bay for the rear ram. The hydraulic fittings are located within the spaces accessible from underneath...I recently had to replace the lines, so this is experience talking ;-)
From the interior, an accordion panel covers the front ram and mechanism, and the rear mechanism is minimally accessible from the far right end of the slide, which in our rig is the kitchen. I could reach the hydraulic access for the passenger slide towards the rear by removing a trim piece and squeeeeeeezing my arm through to reach the connections.
The rams for the bedroom are accessible through panels on the exterior that are 'removable' although not easily. I've never messed with them, but do know that the panels are cut out for removal.
On the driver's side, the rams are accessed (both front and rear) from underneath the coach - albeit much more easily when the slide is out.
I'm not sure that this helps, but thought that I would make the suggestion at least.
