5k is pretty doable on just about any oil.
What does the owners manual say?
Yeah, I would say that's pretty severe considering dust conditions, dry grass, high outside temps, and the heavy towing for 75% of the miles used. "Normal" might be city driving, very little towing, and no dusty conditions. This was far from that, owners manual or not.
