Sliding Closet Doors in 2013 3402 RL

[Dmcgrew]

I keep having problems with the closet doors falling off while traveleing. These are the 4 piece sliding doors with mirrors. I have replaced the hardware several times and continue to have them fall off the tracks occationally.

Today the door fell off and broke the frame. I should be able to fix it but wondering if anyone has found a way to repair or replace them so that the problem is corrected. Any ideas?

Any information would be helpful!!
