Not over 30' either, but plenty of trips through the Cascades pulling upwards of 10klbs or so with a 24' tag trailer, 28' overall length. Bone stock truck with little P tires and no extra springs in the back. She is saggy sometimes, but pulls and stops the trailer well.
For occasional/weekend warrior use, I'd do it and a new 10 speed eco boost will annihilate my 5.3 Chevy doing it.
If I was working my company truck like that daily or even weekly, I'd want a 3/4 ton, but it does the job fine...occasionally.
Ideal? no. Capable? Yes.
