Clunking under dash

I have a 2005 national rv dolphin . I have a loud clunking noise under my dash on drivers side. I have literally torn the entire dash out and re secured solidly. This clunk especially bad when i go over bump. I can sometimes feel it thru the brake pedal yet everything down to the frame seems secure. Has anyone had anything similar and if so how did you track it down.

Clunking under dash

Mine has a plastic liner that is not firmly attached to the underside of the dash. Check to see if it is loose. I put several strips of 2" double sided foam tape between the liner and the dash to stop the clunking. Also, check to make sure that any wood plywood under the dash is secured.

Clunking sound

I have a 99 Tropical and had bad clunking on pass. side. I found a piece of square tubing which holds the dash etc. to the frame had sheared off and was broken. It was hard to find because the 2 pieces were fitted together in such a perfect fit u couldn't tell were broken. Got it welded up and no more clunk. I thought it was a loose dash.
