Last time checked...Ford has the most half ton models, but the other OEMs has many of their own
Marketing model designation is at best confusing and I never really use them, unless talking to someone using that reference.
Best to use 'REAL' designation that is NOT confusing, nor changes over time. "Half ton" covers GVWR's from the low 5,000's to just under 8,000 lb GVWR. Ditto RGAWR...they range from low 3,000's to just under 5,000 lbs...but if you use their 'REAL' designation...a 7,400 GVWR is the same from the day it left the factory...to the day it is crushed for scrap...of course the wear and tear will reduce it's ability greatly...or not depending on how it was maintained
Take JIMNLINs post above and quoted below...they are all 'half ton' or F150's, but if everyone referenced them by 'REAL' specific terms, there would be no confusion.

Ford markets several gvwr/rawr packages for the F150;
#1. 7850 gvwr...4800 rawr....2500 lb in the bed payloads.
#2. 7600 gvwr...4550 rawr... 2200 lb in the bed payloads
#3. 7050 gvwr...4050 rawr... 1800 lb in the bed payloads
#4. 6800 gvwr...3800 rawr...1500 lb in the bed payloads.
Payloads are a estimate as only scaled axle weights will give any truck its real world payloads.
Then the other way folks 'try' to continue to use 'half ton' by adding to look for how many wheel lugs they have....or....whether they came from the factory with passenger class tires (P class that has to be de-rated a min of 9% when used on pickups/SUVs/etc) or with a higher class (light truck tires...LT, which do NOT need to be de-rated)
Why refer to these 'unicorn' as many say...as a 'fake half ton'...more to try and get this across, but marketing verbiage is the basis for most all who are into non-specific reference to their vehicles...wonder when one of the OEMs will come out with a marketing model called: "The Super Dupper, King of the Hill, Bad@ss" model...toss in a very expensive metal's name...works for credit cards too...
{edit}...moving both the TV and Trailer takes the same amount of HP, therefore fuel. No matter which class TV you have
All factored by the ICE architecture, type of fuel, frontal (CX) of both, rolling resistance (extra wide tires has, generally, more rolling resistance than a narrower tire), gearing, pumping losses, etc, etc...
So of course, a lighter everything will take less HP to move it and keep it moving
