Generators
We just finished a nine-month cross-country trip with our 20-foot Prowler. Great fun and very few issues. We used a 110-watt solar suitcase (Renogy) which worked well and we rarely needed a generator....

You can not discern 2dB with the human ear.
Most people can.
The dB scale was set up the way it is partly because 1 dB is the smallest change that the human ear CAN discern.
And 3 dB is twice the audible power.
3db is twice the measured amount of 'induced energy' in the test instrument
It takes approx 10db measured gain, for the human ear to detect it as a doubling of sound level aka "that new amplifier sounds twice as loud as The old one"
Scientifically 3db is twice the sound energy
But to the human ear it is Not! Twice as loud
