A Mack "Manager" Midliner, actually a Renault. The one I drove was this size but only had the side rails on the front section and had no lift in the rear. It was the largest truck in a company with a dozen or so warehouses in Florida that ran smaller Isuzus and a few Mitsubishis, and they wouldn't have bought it outright but it belonged to another company they bought out. Naturally it sometimes got called upon to do some hauling for other warehouses that their trucks just couldn't manage (pun intended) and I loved driving it though some drivers were afraid of it's size (wimps), and then there was Lulu, one of our best drivers but she couldn't reach the pedals in it. The company was so cheap that for awhile the side rails were ones I built myself out of wood but they finally had some steel ones made (heavy bastards they were) and a step put on to make it easier to climb on & off, after I'd moved up from driver to assistant warehouse manager of course. Our big problem was finding a repair shop that could deal with it in our area, which is not really a major metropolitan area, and that would put up with the company's slow pay. In the company's defense, we had a lot of problems with slow paying customers too.
