Looking to buy a diesel but I'm not sure that I haul for enough of the year to keep it happy. From what I understand, the happiest diesel owners haul loads frequently. I am in metal roofing so I will be hauling an 18' trailer and sheet metal a couple times a week for about half the year. Is this enough to keep the engine happy? This truck will also be my daily driver when it is not used for business.

Thanks in advance,
