Under the left rear of this coach, there is what looks like a hyd. ram with a hose coming from under it.
Its leaking hyd. fluid.
The end of the ram appears to be flat on the end, and there isn't anything at the other end for it to attach in any way.
I don't know what this is, or if it just needs to be removed.
I know it isn't to push out the back bumper.

Any ideas about this would be welcomed.

Lee,
Without any further info, I'd have to guess, based on your coach listed in your signature, that what you're looking at is what's called the equalizing cylinder. There should be more than one hose emanating from it. If it is in fact an equalizing cylinder, it's there to balance out, the two rams that are used to extend and retract your bedroom slide. It keeps the "balance" between the two of them so that one does not act stronger or weaker than the other and, the result would be that your slide would bind due to unequal pressures causing one side of slide to move ahead of the other side.

But, it is ISN'T an equalizing cylinder, then I have no clue.

Checking back, after being notified there was an answer.
You are probably right about its use.
There is also a leak in that area, and I'm guessing its a seal.
I believe its going to be a job to replace any thats leaking. And you might as well replace them all while you are at it.
Not sure if its an at home job or not. I can't lay on my back for more than a couple minutes.
Thanks for the info.
