And I need to correct my statement about the rollers. 4 out of 5 of the outside rollers have weight on them. Also noticed once I got the trim removed there is another roller inside, under the slide. The weight has the floor bowed on each side of that "extra" roller. This roller is almost exactly in line with the roller that free spins. I'm gonna add 2 casters on each end of the slide. One under the dinette and one under the couch. The idea of a caster rolling over the linoleum isn't great but it beats replacing slide mechanisms and tearing the floor.
