Mermaid Heat /Cool System Replacement

Has anyone replaced their aging Mermaid with the same model or a different option?
mine is a 1998 unit, is still working, but I'm just planning ahead!
Thanks

Rich,
The condensation pan on my old Mermaid corroded out and leaked water. Eventually, unit stopped cooling...
The unit was replaced with a Dometic DTG16 Reverse Cycle Heat Pump With Smart Start. This version has a composite pan - no rusting. The control panel also had to be replaced.  After a year, both heating and cooling are very good. 
BUT, I was hoping my Honda Generator 2000 series would support powering the Dometic at anchor with the Smart Start. Technician at Dometic stated 40 amps are required for a milli-second, and the 30 amp rated generator will not power the compressor on. If anyone has a work around for this please post.

Thanks for the note, was it quieter than the mermaid? I find the mermaid when it cycle goes on and off through the night can keep us up. Take care, Rich

Rich, the new unit is a "bit" quieter. The fan speed can be adjusted as well, but only helps a "bit". Dometic offers a sound insulator cover for some models. But the heat or cool air when needed, more than makes up for the noise of the unit...
