We have a small hydraulic leak... Is it a chassis problem or a slide-outs/jacks problem?

About ten days ago Eric found a hydraulic fluid leak in the back of the motorhome, behind our side radiator. The leak is slow, for now.  Hydraulics run our jacks and slide-outs in and out.  We are too far from Iowa to consider a visit to HWH in Moscow.  Checking  the HWH website provides good news...  Central Point RV Center in Central Point, Oregon is a HWH Master Service Center.  Eric called and made an appointment for Friday.  Glen told us to come in as soon as possible and he'd look at the leak.  He's given us permission to spend several days in their RV lot, waiting for our appointment.

We arrived at Central Point
RV Service Center.

Glen came out, took one look

at where the leak is located

& told us we needed work

on the motorhome's chassis.

The leak is coming from the motorhome's fan drive motor, part of the motorhome's chassis.  We have a Freightliner chassis and Glen gives us directions to Pacific Power Products, the nearest truck repair shop that works on different makes of diesel chassis, just down the road in Medford.
