A number of folks have asked about making adjustments or alignments to their slides. I recently made a height adjustment on my bedroom slide so thought I'd take a few pictures to help explain what I did. I used the same method to adjust the front slide on our 01 Contessa. My experience has been that the rear of the slide drops or sags. This is normally due to the weight of the closed slide causing the outboard roller to indent the floor. The floor is normally panels of luan or OSB sandwiching a styro-foam type material. In any case, the fix is to give the roller something to ride on that won't give. Looking at the first pic, you'll see that I was dealing with about a 1/4"+ sag. First step is to lift the slide enough to give you access. I use a High Lift (farm) jack as shown. (For the front slide, I had to use 2 jacks). Lift the slide just enough to be able to slide the new plate in place. Then locate the roller and measure the distance from the inside of the outer slide wall to just inboard of the roller. The bedroom measured 19". (Finding the roller was a bit of a challenge as they are inside the nightstands and covered by the carpet). If you are dong the front slide, BE SURE to measure to the inboard side of the inside roller as there are 2 holding the rear of the main slide. I selected a 36" x 3" piece of steel, 3/16" thick, cut it in half and "glued" the 2 pieces together with Lexel, yielding a 3/8" lift. 18" works because the roller does not contact the very inside of the slide outer wall. If you take this approach, be sure of your measurements as the last thing you want is for the roller to come off the new metal pieces. Drill 3-4 countersunk holes in the metal plate to keep it in place. Align the plate and mark the holes on the slide floor. If you locate the holes near the outer edges of the slide, you'll be able to drill into the Al frame. Apply Lexel to the plate where it contacts the slide floor and screw the plate in place. That's it if you've measured correctly. If you have ?s, post here or email me.
