We have a 2010 2900 mk and when we fire up the furnace there is a loud humming noise when we turn it on.It sounds like the tubing in the furnace and it only lasts about 5 seconds and then it is normal.We have friends that have a tent trailer and it wakes them all night everytime it kicks in.It's loud enough you can hear it a couple sites away.Any thoughts to make it quiet would be great.
