Hydraulic leak

So we had the coach in storage for a couple of weeks after it being used all winter, and during a trip to check on it at the storage facility noticed that there were two puddles of hydraulic fluid on the ground in front of the tires. . The drip is onto the axle, leaf springs and belly pan. Lost about 12 oz while parked in storage. Which released the pressure in the slides and they kicked out at the bottom and sucked in at the top. We tore the underbelly completely apart, and found a couple small drips of fluid on one cylinder, the supply line and at the end of one cylinder. I went around and tightened all fittings I could reach, but none were loose (could hardly turn any of them). After I tightened and wiped down all the drips, we ran the slides in and out several times, and have not seen anything else leaking (not even from the end of the one cylinder). Has anyone had a similar leak occur after a prolonged use then storage? We are full timers and rarely does it sit in storage.

I had the same thing happen on mine and it ended up being a leak on the wiper seal for my hydraulic cylinder. It didn't leak while the slides were open but had a steady drip while they were closed. No easy fix for mine, I had to cut a 3 sided access panel out of the underbelly under the cylinder to get the part number and order a new one. It was a messy job but is something a DYI can accomplish with a few tool and some time.
