My new fixed may help you

Just want to put this information out. In my last 2 or 3 trips this noise came from the slide behind driver. It sound like "woooop woooop" when it is going over speed bump or some incline hill or break hard. They found the guide plate under the slide were fasten with nails and they all came loose. They replaced screws and the noise is gone "one month before warranty expired" .

Good timing!

Thanks for the heads up. I'll be picking up my 2016 2401W in a few weeks, and the more info I have, the better I can deal with the unknown.
Have a great day!
