Lots of good answers proposed .
APT and Jeremiah make the most sense .
If you have sway it is necessary to weigh all of your axles hooked up and not hooked up .
You will be amazed at the shift of weight on each axle hooked up .
Heavy tongue weight mitigates sway .
A half ton will limit the tongue weight necessary to make your rig the safest .
With a 12 % to 15% tongue weight you have more controlled weight between the hitch and the trailer axles .
Commercial trucks have their axles at the ends of the trailer .
Travel trailers have all of that uncontrolled weight behind the centered axles and that weight is on a lever .
F250 for big brakes , heavier payload to take that GOOD heavy tongue weight .
The heavy duty components of the F250 will last longer than the lighter weight components of the F150 assuming the same load usage .
The scales are your friend .
If you can adjust your tongue weight upward that would be safest at any speed .
