Loadliner 300 The new Loadliner 300 series was added in 1968, a slide/sweep method rear load packer. The 25 yard truck shown here is from 1976, the year that a smaller Loadliner 100 series replaced the old RL-15. Note the position of the slide cylinders, which were originally mounted rearward of slide panel guideway. 9/7/04 © 2004 Eric Voytko All Rights Reserved Photos from factory brochures/advertisements except as noted Logos shown are the trademarks of respective manufacturers
