An old topic, but I saw something somewhere that reminded me of it. Am I ever glad! Hadn't run mine for about a year.
So, got it fired up (After remembering HOW to do it). Connected the trailer line to it, and fired up the a/c. Temp dropped from 110 to 80 in about 10 minutes.
I can't run the a/c on house current due to low amperage circuits, but the genny keeps it going. So, ran it about an hour, got the trailer cooed down inside, AND gave the genny a workout.
Timely reminder.
