I will share our experience.
Bought a 28' TT (rated 1/2 ton towable at 5k pounds) Then traded in our 1997 Suburban gas 1/2 ton (too any miles and worked too hard pulling) for a 2011 Silverado 2500 Gasser. Pulled the trailer with ease.

If I would have done better homework we would have bought the 3500 Silverado diesel.

So guess what? Several months ago we did that to get our 5er.

Just a suggestion, think safety. Think torque and wear and tear.

Go bigger first. It is OK to have too much truck. It is not OK to not have enough.

Good luck
