virtually never come up for sale mate,the material is rarer than the frames.however regular trimmers will be able to make a bunk for you.alternativley search 'argos' on here as one of their camping beds can be used on the old dormy frame.

Hi,
I've im the process of restoring my 68 dormobile bay, i've ended up with two pairs of bunks, both sets are in very good condition (inc fabric), I only need one pair so I'll let a set go...
PM your email address and I'll send some pics (earliest will be tommorow though).
