I'm not a typical RV owner. I'm full time in my coach and I drive it every few days. It's never been stored since I've owned it. I'll let Detroit Diesel and the laboratory decide whether or not I change the oil at the time I change the filter. That's my perception of "reality", what the manufacturer and the laboratory tell me to do. If you have a four stroke diesel and you seldom drive it your oil change interval should be much more frequent.

Here's what Section 3 of a Detroit Diesel Truck Engine Manual (covering the two-stroke engines including the turbocharged 6V92) states:

"For highway trucks and buses, used for inter-city operation, the oil change interval is 100,000 miles. The drain interval may be extended beyond this point if supported by the results obtained from used lube oil analysis; it is recommended that you consult with your lube oil supplier in establishing any drain interval exceeding 100,000 miles."

"For city transit coaches and pick-up and delivery service, the oil change interval is 12,500 miles. The oil drain interval may be extended beyond 12,500 miles if supported by used oil analyses."

Your operation more closely resembles the "city transit" or "pick-up and delivery service" than it does the "highway trucks and buses, used for inter-city operation" operation and so the 100,000 mile oil change interval would not be appropriate.
