I have a 2013 26h vista and I am having a heck of a time with the thunder sounds tha come from under my rig when I hit bumps, does anyone know how to fix, support, stiffen, and or eliminate this noise. I am tired of taken it to the dealer with no help from them.

I am also interested in a way to dampen the "booming" sound from the chassis. I've thought about adding stiffeners or bracing of some sort but have done nothing yet. Neal 2013 26HE

I am thinking this weekend of running a Piece Of Unistrut down the length of the heat shield as a stiff er and possibly supporting it at an angle to the frame. The has to be a way to keep it from oil panning.

It would be nice if he would've showed us what he did to fix the rattle

Hi guys. Had the same problem with mine. Every time you hit a little bump on the road you could hear the tin rumble underneath. I solved the problem by running 1" angle iron across the leading edge of the shield, tack welding it to the frame then lag bolt the shield to it. Then i think there are two cross members that I lag bolted the tin to. Solved the problem.

If I remember correctly the shield went over the cross member and the cross member had pre-punched holes and I just drilled into the shield and lag noted it. You might get away without the angle iron on the leading edge, I just didn't want to be doing it twice.

Hi, the thunder tin noise is not from the vertical heat shield, crawl under and you will see another one that is the width of the chassis frame and goes about 5 feet toward the back. When you put your hand in the middle and push up you will hear that dreaded noise. i added a post on how I fixed it...
