You cannot have too much truck, but you sure can have too little. Think about the future as well. Most start with a nice small trailer and then in the future go larger. Trucks are expensive and to have to purchase another one is knee buckling. Get the bigger heaver duty truck you can. I would skip the three quarter ton. Not much of a gain from a one ton in carrying and pulling capacity. Half or one ton. We started with a tent trailer, Class C, Big Horn fifth wheel, now do to my health problems a SOB ( some other brand ) class A. I had a one ton diesel dully and loved it.
