We just picked up our new fifth wheel today. I noticed a high pitched whine from the electrical panel. The pitch seemed to change depending on what items were on at the time. Is this normal? Our 2009 had no noticeable whine.

Is the inverter working in bypass mode? Mine was wired incorrectly and I had to get it corrected. When it is under load the inverter will put out a pretty good whine - especially if you are running anything other than a residential fridge off of it.
If the display says is is in bypass then I can't offer much help. If it isn't in bypass then you have to hit the button on the inverter - the one on the remote panel won't turn it off - to see if it will cycle over to bypass mode.
