It depends entirely on the brand of slide mechanism you have and type seals used. One 5er we owned had an inward bow in the side-wall because the slide adjustment was too tight. Took it to an RV service shop to have them re-adjust the mechanism so the wall would straighten out. They said to leave it alone the damage was done, no way to straighten the wall now.
Search the internet for your brand mechanisms service manual if you are a DIY person.
