Rattling noise under my 2005 Lexington

New to RVing and the forum. Recently purchased this '05 Lexington. Has a rattling/ pinging noise that seems to come from under passenger side midway back. Mostly on acceleration but sometime just idling. Performance not affected. Ideas?

There is an exhaust shield (metal plate that dissipates heat) near the catalytic converter. If a weld is broken, it may rattle. Look for a flat, vertical steel plate mounted to the frame...check where it is attached.
