Can you just manually open and close most of them?
Yes, Unless it binds in it's rack.
an average slide is 300-400-500#.
You might need 2 people, mechanical know-how and some tools to get it back in before you can move the rig. That's where the malfunctioning slide issue is different than a malfunctioning water pump.
Do a google search of electrical vs hydraulic RV slideouts to gain info.
How often do people have slide issues ? If you ask individual owners who have owned one or a few rv's, you get one answer. If you ask the guys at RV repair shops who see multiple rv's 24/7 , you will get another answer.
Its a room that requires a large hole in the side of your RV , that moves in/out that requires, a seal, a motor, a track, some kind of header and a moving floor that goes bouncing down a highway.
But it offers you more room. Only you can decide.
