"An example of this is towing an RV with your family and the variety of gear that comes along with that in the truck."
@ccw Your are examples are definitely valid but I would add that there is a large overlap between the two use cases unless we are talking about an extremely large travel trailer or 5th wheel (and/or a large family)
A 250 provides ~1300lbs additional payload vs. my F150 that I can utilize which, for me, will be mostly applied to a larger camper (32ft, 7500lb dry). Cargo in the truck will more or less remain equal (including just my wife and I) and I will still end up with a healthy reserve.
The benefit of the Tremor is that I could use
all of my 2720lbs and still be confident that I have some reserve, while remaining legal.
An equivalent fifth wheel of the same length, brand, features, etc is in the 2100-2200 pin weight territory and would put me in a 350 from a legal perspective. This would follow your example perfectly.
