Am I missing something here? On these threads someone always jumps in with the brakes on a 3/4 having more stopping power.
Maybe it is different with larger trailers, but my trailer brakes stop the trailer and my truck brakes stop the truck.
If you don't feel the trailer brakes engage and hold you need to look at your set up.
If you need a 2500 or larger that is what you need. Just remember that the repairs will be more expensive, registration usually costs more, tires are more expensive and around town gas mileage will be much worse.
If the TV is also a daily driver,how much are you willing to pay out for the downsides of a truck that you only use to its capacity for 60 days of the year?
