2009 salem 392RLDS slide out help

[rochockey83]

Hey everyone, newbie to this group. So i have a seasonal camp site and just upgraded my camper from a 2006 Sierra fifth wheel to a 2009 Salem (392RLDS). I'm just trying to figure out what system i have for my slide out. I know its hydraulic. I had an issue getting one of the two slides to move in properly. I used a monkey wrench on the bar and was able to retract it in. I believe its a through frame setup but just want to make sure. And until i can get the slide power working properly i will have to manually do it. I mean once i open the camper up for the season it stays open until i close it up for the season. Also does anyone know where i could obtain a manual for this camper. I have tried forest river website but they only go back till 2015. Any help would be great. Thanks!!
