Sure does!
Frank is the rescue truck. Betty does the heavy hauling!
Betty's leaf spring pack is twice as thick as Franks. Knock yer fillings out driving over a shadow!
I swear the frame flexes before the springs compress.
Put 1 cubic yard of crushed concrete in Frank and he was P1SSED! Filled Betty's bed as much as would fit in the bed without spilling over (almost 3 yards!) an she squatted about 3 inches. Needless to say I drove that load home @ 25 mph with the flashers on.
Only 2 yards per load from now on!
Betty also has the load sensitive rear brake proportioning valve if anyone wants to know.
