An Etymological Dictionary of the German Language/rumpeln

by Friedrich Kluge

rumpeln, vb., ‘to rumble, rummage, throw into confusion,’ from MidHG. rumpeln, ‘to make a noise or din, fall with a clatter’; probably an intensive form on account of the p. Comp. the equiv. MidE. romblen, E. to rumble; allied to Du. rommelen, ‘to make a noise,’ the mb being assimilated to mm; hence Rummel means ‘lumber.’
