Hi Carol, we have bought the 540/4 with a fixed rear bed. The Omega is a nice van just a shame about the build quality and after sales/warranty claim time. The rear Bed/Dinnette does'nt make a very comfy bed to leave setup all the time. Plus now theres damp in it after 21/2 years of ownership, which was the last straw. The dealer who sold us the Omega is selling us the Pastiche, so he knows the van inside-out. Thank you for the good wishes, hope all is o/k with your van,Bazz.
