we have a 2015 Rushmore Lincoln 5th wheel we have owned for 1 month. We just discovered an apparent reservoir with maybe hydraulic fluid in it located near batteries. Cannot find any info in our manuals about it. Any info would be appreciated. I am assuming it is for leveling system and/or slide. Wondering also what type fluid recommended. Thanks for any info.
To check or add fluid, ALL hydraulics, in your case slides & All of the level up jacks, must be retracted then fluid should be within 1/4-1/2" from the opening & if you add 15w motorcycle fork oil to the reservoir it will help with possible popping/creaking of your jacks.
