So we have a new Greystone 33ck. I go to use the bathroom and notice the little wimpy vent fan that the factory installed (really). When I purchased my Jayco they at least realized the importance of properly venting the bathroom for steam and other smells and installed a fantastic knock off fan! Why would heartland skimp on that 150 to 200 item?? That should be standard, now I have to go buy a MaxxAir fan that will mount on the existing vent. I looked at the fantastic fan but don't want to disturb the roof. Sorry for the rant but i am sure others are feeling the pain.
