Maybe missed it, but without knowing 'which' half ton you have...talking
about the trailer is putting the horse before the cart
You have lots of advice, but I'd like to see the TV's GVWR, F/R-GAWR, engine
size, and a confirmation of the diff ratio.
2014, so the close ratio automatic with the double OD (it is an
automatic, right?)...so the diff ratio can be a MPG ratio...up to a
point and that depends on the size of the trailer/how you load &
pack/where you drive/etc
There are several variations of 'half ton' from the OEMs. Some OEMs have
more flavors than others. Why am asking for the GVWR and the front/rear GAWR.
The payload has some bearing on the rear GAWR, but not definitive enough
for me if I was to be towing heavy, as the OP's comments indicate
Does your TV have the integrated trailer brake controller?
Then the obligatory questions on modifications and upgrades to the
'stock' vehicle.
Over sized wheels/tires?
Lifted? If so, suspension or body or both?
Engine/tranny mods? Meaning tuner?
These affect the tow and carry ratings of the truck. I don't know
the OEM tire OD (rev's per mile is the better unit of measure) and
if your tires are larger...they *REDUCE* the ratings by an effect
change in diff ratio
A picture of your drivers door labels would be most helpful
