Slides may squeak, but they must be moving in or out to do so. I think your problem may lie with the Ford chassis. Spring pins, torsion bar bushings, all in the fwd end of the last of the coach length, near the doorway. If that's where the sound is, probably the reach suspension. Under your seats its maybe the front suspension. These joints do wear out and need to be checked every so often. The bumps clue me even more to check suspension. Enjoy your 378, great coach.
