If you're buying another tv, and a large trailer is in your future, go right for the one ton, the cost is about the same as the 3/4.
1/2 t are setup to ride and handle like a sedan these days, and that's no good for towing. Now that's spilling into the 3/4 t range for some reason.
I'm real happy with my new 3/4 t, and it tows my tiny trailer just fine. For me, the increase in capacity means I can worry less about carrying stuff in the bed, passengers, and the weight of the trailer tongue.
I towed close to 30,000 miles with my 1/2 t and it was never "white knuckle", but my tiny trailer weights 3500-4000 loaded, with about 500-550 on the tongue. That didn't leave much payload in my 1/2 t, and the rear suspension suffered for it when I also brought along a lot of gear, bottoming out more than a few times.
The new 3/4 barely moves when I lower the tongue on the ball, and doesn't mind a bed full of generators, water, gas and firewood.
