2004 Flagstaff 831FKSS with slow moving slide-out

[lkeul]

Looking for a little help....I have a 831FKSS with a electric slide-out, it goes out just fine and at a reasonable pace, but is having trouble retracting, it is very slow. I have lubed the system well and have checked everything I can think of, I am on a solar power set up with 4 deep cycle batteries but this is happening when I am connected to power. Not sure what I should be checking next. Any help would be greatly appreciated....Thanks

Hello lkeul. This might sound weird but on our 2013 Rockwood 2703WS, the slides actually work better with the door or a couple windows open. Especially putting them in. Seems to relieve the pressure inside. Just saying.
