A close friend of mine is considering at purchasing a new 3500 crew cab with a dump body. The truck will be towing a 10,000 pound equipment trailer all day long but making any where from 25-30 stops a day. He runs a lawn care business and his average total miles traveled in any given day is only around forty miles.He plans on keeping the truck for at least ten years.He presently has two F350's with gas motors, I'am trying to put him in a new Ram, I just don't know if the 6.7 is really made to go 10- 15 minutes shut her down, start it after 30-45 minutes and repeat it over a ten to twelve hour work day.Any suggestions would be appreciated, Frank
