House fuses,chassis fuses. Itasca Cambria 09

I see the chassis fuse box but most of the fuses are 30 plus. Where did they hide the smaller panel. I looked under the dash on drivers side.

House fuses. Is that ALL there is ,the ones on the converter as i enter the coach.A few wall plugs and appliances?

On this trip I lost power to my hydraulic jacks. It is an add on that sits next to the driver seat.There is a fuse on the control box but it checks ok.

I left the race track yesterday and my step never retracted, didn't notice until I parked curbside.
