Where is hydraulic reservoir on Class C?

This has probably been already asked, I just cant find any post. Had the Equalizer auto leveling system put in some years back. I have a Melbourne class C. For the life of me I cannot find where the hydraulic reservoir is. When I asked the dealer who install, they said most likely under the hood but that was awhile ago. I no longer live near the installer. System is working fine, but I would just like to know and check level. Thanks.
