We have a 337RLS and are just returning from a trip to Mexico so it has been shaken a lot on some rough roads. Yesterday the dining room slide started hanging up on its way out - it would hold at the top for a couple inches of travel and then jerk out, This repeats several times on the way out. Going in is normal.

We have a dealer installed slide topper and I wonder if it may be hanging up.

Any helpful suggestions would be appreciated. Does anyone know how to lubricate the slide topper?
