Your unit is the same as mine. I use baby powder on the rubber sears and have no problems since I started using it. You still can take a look at the slide out gear assembly if still everything is OK. I have a manual with details. Jayco could have made the space an extra inch, but it is what it is. I made the front closet also full height as it was useless those low closets. Done lots of mods to make it a four season unit.
