Noise while driving - belly pan?

jgpell14

Hello, we have a new 2022 tab400 BD. I have a noise while driving (50-60 mph) that's driving me nuts. It is not a heavy clunking of the hitch. It is a shallow/hollow banging that has no relation to bumps or speed change. My primary culprit was the tongue storage, but I've ruled it out. I'm now thinking it is the belly pan. If I get under it and push it, it is floppy and sounds like it could be the cause. What do you think? Has anyone else had this problem? Thanks!

Check to see if the belly pan is still attached on all four edges and that the screws are tight.  I had the rear screws detach and disappear while traveling.  The aluminum bar that the screws were screwed through (and then into the coroplast belly pan and then into the frame) had then dropped down and had been pretty well ground away by dragging on the highway.  There really isn't anything to attach to in the middle of the belly pan.
