I am on my second rear kitchen TT. Love the counter space and available storage space. have not had a problem with cabinets/fridge coming open. The cabinet that I have the most trouble with is the one over my sofa in the slide-- running length wise of the TT and that is my fault. I have plastic dishes and tend not to pack that cabinet full, so stuff is light and tends to slide.
I am now looking for a med length class A for full timing and am having a hard time finding one that I like the kitchen as well as my RK TT.
