Our diesel truck and 5th wheel have opened several areas of new knowledge for me. I found that most of what I knew about tires only applied to automobile tires and I had a lot to learn about trailer tires.

The diesel truck is similar since there is a big difference between a gas engine and a diesel. My advice is to read the service manual and follow their instructions on oil, oil filters, and fuel filters. Also fluids like transmission and coolant. I have generally used mileage as my guide for the intervals between service, and not time. Many people use fuel additives and talk about them like they were holy water, and I do use them but only when we are between trips and a tank of fuel is going to mostly sit for a month or more. Moisture is deadly to diesel engines and will not mix, unlike most commercial gasolines with alcohol.

Good luck and safe travels.
