Just bought a new 2011 Fleetwood Bounder 35H M/H. M/H is built on the Ford chassis. Noticed an unusual howling noise while crusing on backroads. Noise occurs between 38-45 MPH. Shifted into different gear and noise was still there so it seems to be vehicle speed related and not related to engine speed. Has anyone out there had a similar issue or have any ideas?
Certainly something like this should be covered under warranty. This is the big advantage of owning a new RV.
4 whopping cylinders on Toyota RV's. Talk about great getting good MPG. Also I have a very light foot on the pedal. I followed some MPG advice on Livingpress.com and I now get 22 MPG! Not bad for a home on wheels.
Don't know what Bounder has for a grille now, but back in the early 2000s they had a similar noise problem caused by the grille. Their "fix" for the problem was to glue some rubber gasket material to the back of the grille bars to change the airflow over the grille. Might want to start there, just for kicks.

Its the grill made of tube with no end caps. Air is making the noise when blowing past the tubes at a certain speed. Mine does the same thing. Fleetwood needs to come up with a better grill.
