A couple of years ago I made a Delivery in Queens to a florring company. They guy had just switched over from UD's to Hinos. He siad the UD's were wearing out after 4to 6 years because of all the constant weight being put on them & the stop & go traffic.
He speced his Hinos out where there was a toolbox size small sleeper between the cab & the bed so the weight would be evenly distrubited, he said they were the best trucks he ever owned. Now this was back in 08' I'm guess the trucks were around 1 to 2 years old than. I'd like to know how he feels about them now.
I have to agree that the UD's to wear out if you over load them day in 7 day out, but than again so will any truck. I've had 3 UD's & I always liked them, but I dunno if I could handle a cabover ride anymore, & they hold there resale vaule, very expensive to get into a used one.
