according to the measurements on the Dometic-Waeco website, it looks to me like the CFX-35 is too big to fit in the galley space. The width is 630 mm without handles and the depth is 398 mm. Those convert to 24.8 x 15.7, both of which are larger than the galley space on our 550.
I'm not sure what the difference is between the Dometic and Waeco websites but they do both say dometic. One site lists the CFX-35 and the other lists the CF-35.
Whatever, I sure hope they're still selling the CF model 'cause I'm thinking about getting one sometime soon.
