When we bought our previous RV, a 2005 Cross Country, we also thought the hood was howling. Turned out it was the gross adjustment of the mirrors, They worked OK with the remote but had to use the included allen wrench outside to reposition the distance from the coach. Took a few miles to get it just right.
