Yes we have had lots of issues with slides and motors and towers on our 2015 slide out. We had front tower replaced, wore out tracks since opening was not correct size, dealer repaired with new tower, motor on front end.
Then this one failed again, so Forrest River replaced the 300 to 1 assembly at both ends with a heavier 500 to 1 assembly.
Then about 3 months later front motor failed and would not open, FR replaced with a new motor.
We are hoping all issues are not solved.
PS We only sync each time the slide out goes in not both directions, also with the new stronger motors, the nails that hold the trim started to come loose so replace with bronze screws.
PPS If you hear any clunks the tracks are wearing and must be replaced.
