The doors just never close quite right and there is a huge gap. Making the doors fixed would go a long way towards making the vestibules more robust. However, I have never had an issue of couplers coming off on mine.
Iād be for fixed doors. I never got why working doors were important. š¤ Perhaps the fixed door would make assembly easier - a good thing. š
