Do you know if you have a LCI(Lippert) Frame? Odds are you do. Lippert gets the blame when the Frame is not built correctly. Not large enough gauge steel and inadequate outriggers and brace supports. LCI builds the chassis to the OEM engineers specs, NOT what LCI engineers it. I have seen (Master tech) dozens of LCI frames that do what yours is doing over the years. The problem is, they do NOT build the frame strong enough for the Hole cut out for the slide room. That causes the type flex you have experienced. usually we take a frame flex measurement and then (under warranty) LCI sends a mobile crew out and they weld and install gussets(anything that is needed), to align the frame and reinforce it to get it to specs. Usually what causes the customer to notice the problem is when they have numerous issues with the operation of the slide room. It sticks/jams/ will not go in and out correctly. You are obviously out of any frame warranty. IF LCI, I would contac them and see if you could transport the RV to Elkhart, Indiana for them to fix(you would have to pay for them to do this), or how much they would charge to send one of their mobile frame repair trucks to you to fix. Without having the specific training and knowledge the LCI Frame techs have, you will have a hard time fixing it yourself. Doug
