My 95 has a wet bar.
I think you could build or find something that would be more serviceabe then the OEM unit.
I converted mine to a propane locker and BBQ stand.
Take a look on the pontoon boat store sites.
Our 96 has a wet bar. Way back when I was able to purchase one from the factory for $5000 for a friend to use on a larger yacht. We use the refer for pop if hot and we have shore power. Have never used the sink. Plunked the BBQ on the cutting board on the top.
