The mid seventies Sovereigns were made by the thousands, and could be configured with a center or rear bath - the rear bath models are discernable from the outside by the lack of side windows near the rear. Beds on rear bath models were usually amidships twins with a front sofa that folded out into a double, and were popular with older couples due to the more open bath.

The attraction of center bath models allowed the front sofa visitor or children to access the bath undisturbed.
