We have a 2007 Springdale 290CT with a 13' slide that has about 1/2" of sag in the middle. I talked to a local rv repair shop and they said their repair would be to remove the trim on the inside, jack...
We tend to store our TT under cover with the slide out, and we have a 3x13ft. slide. Now wondering if we should store it with slide in to prevent sag as discussed in this post ?? Also wondering if gentle pressure from an external jack in middle of slide when out might help prevent sag ??
