I have posted this in other places, the answer is the same,:
You must know the weight of the trailer you want to pull,
You must have a trailer brake controller,
You must know the tow rating of the specific truck you are looking at.
All manufacturers have a tow guide, but you must know the options your truck has, just becasue it is a F150 or toyota tundra or this that or the other is meaningless, SOme are great tow vehicles some are not. They come with different parts. Different engines, different gears.
If you don't want to take the time to learn the difference between a 3:31 rear end and a 3:73. Or what the "liters" mean on a truck, I strongly suggest you buy a F250 ford or a 2500 GM. Not sure what dodge calls there 3/4 ton... probably a 2500.
