Question Is This Severe Usage?

We are snowbirds so we have two periods of intense towing per year and the rest of our travel is getting groceries. Here is our mileage pattern for the past six years:
Year Mileage % Towing
2004 19,000 37
2005 20,000 24
2006 16,000 28
2007 20,000 25
2008 24,000 44
2009 18,000 33
The trailer is a 10,000 lb. fifth wheel. Truck will be a 2011 350 6.7L 4X4 SRW.

In your opinion, would this use pattern put me into the severe use category for maintenance indicated in the table on page 84 of the 4th printing of the diesel supplement?

A more rigorous maintenance schedule is never going to hurt the truck.
