I have a tow company, in june of 2013 I towed in a pop up camper with a broken leaf spring being pulled by a NV. The owner had a fleet of them for his HVAC business. He had emptied it out for a camping trip. He had 80,000 miles on it and not one break down. He said he keeps it loaded to the max and delivers Heat Pumps and Furnaces via a trailer that he keeps a sheet metal break mounted in the trailer as well. he said he tortures his NV on a daily basis!! So this is why I went out and got me an NV.
