ive towed w/ mine (18' open/flat) hauled cars and motorcycles (more
than 1300miles 4 sep. times)...TWICE w/ the wife...she slept fine & never
complained (other than my making 'er go 550mi between stops).

no drone, quiet as stock @ steady throttle/2000rpm

Are you running the MBRP muffler or NO muffler??
