Fluid for Dewald Hydraulic
I have a 2002 Sun Voyager with a Dewald Hydraulic system for the jacks and slides. Need to add fluid to the reservoir tank and the manual says either ATF or hydraulic fluid depending on what Gulfstream put in it. Fluid is violet in color so I am assuming hydraulic fluid but does anyone know the type, brand, weight, etc. I did some research and came up with Castrol super blue but I don't know which one is required.
