Do we have any recourse?

I would think someone on the manufacturer's staff should be leading the way towards a solution, if it indeed is a mfg. fault. Just off-hand, the shower door situation might be easily fixed by a change in procedure, holding the glass panels apart during transit. It could also be that replacing the glass with acrylic sheet solves the problem. Might be many ways to a different resolution of the problem.

Unless Keystone has every owner complaining about non-operating windows (I don't know whether that is or not the case), then it would seem that MB's trailer has a unique issue. It may be that the frame is not right and by typical installation process, it is racking the window jambs so the window doesn't operate correctly.
I wonder if the OP might know the reason for the windows not operating?

I don't know directly, but the service mgr. told me that the rep told him that the windows were poorly designed and manufactured. I guess they can't use different ones in a rig designed for those, but I wonder how other Tracer 230s are doing with their windows. Right now, two of the six won't open, and one has been replaced three times. Originally, a third one wouldn't open, but they fixed it successfully on the first try.
