Doesn't matter if you use synthetic oil or regular oil, contaminates and fuel dilution will be the same. Use the oil life monitoring system and I'll bet it will call for a change well before 14,000 miles if you tow a lot. Send a sample to Blackstone Labs and they will give you a good idea of oil change frequency.
PS, great minds think alike, the above post was made while I was typing.
I believe on the DEF trucks the oil change monitor is strictly on the 15K miles. Chris
