<<The downside to the compressor units is the noise. You can hear the
<<compressor running and kicking on and off.
There may have been something lose that was rattling, on your fridge. There
is also a computer type fan that sucks cold air from under the van and blows
it over the condenser coils in the fridge. On mine the fridge is no louder
than the fan, you can barely hear it inside at night.
