Hey All, I'm wondering if I should be concerned, when I've got the pup plugged in to shore power, my converter under the seat bench, really makes a pretty loud buzz. Almost to the point of being distracting when spending time indoors. So I am aware that the unit is 20 years or so old ( not sure of the make/model right now), but are new converters any quieter? I do NOT have a battery connected currently, and it does not appear that this pup ever had one in-place. I might be interested in that some day, but it's probably going to be rare that we will be camping somewhere without shore power available, in all honesty. So it's function is simply to take the 120v down to 12v for my lighting. Is there a way to simply not bother and have the shore power go direct to my interior outlets? I could live without the 12v lighting probably?
