What did you do to your Class A MH today???

Just added 2 1/5 liters (roughly quarts) to the hydraulic jacks/slide out reservoir! :E Rear slide didn't want to fully extend last weekend. We had the unit serviced recently and have only used the jacks and slides twice since then; don't know if the tech neglected to fill it or if there is a slight leak. When we get it parked in it's usual spot at home I'll run the jack and slides and watch for a leak. It's in the driveway at the moment and don't want to do that here. Waiting on a call back from the tech who has been excellent in the past, can't see him missing this. Hope we don't have a new problem developing!
