anyone have expierience with the aeroturbine?? 4040xl or 4040??? which one sounds better I dont want drone I have a 5 month old and take long trips
IM a dealer and i am not aware of that, it was never told to me or brought to my attention thru any correspondenceI have the 4040 and I get drone when towing. But just cruising around, AWESOME sound. I heard, if you order it from the Aero Manufacture website, you get a 30 day trial. So if you don't like the 4040 you can exchange it for the 4040xl. Can anyone confirm?
