An original 1 ton or short wheelbase (137") 1.5 ton should be fine.
I pulled a 61 Ford f350 with a Detroit Diesel 6V53T, about 300HP, and did better than half the class, about 20 trucks total, no problems with the truck or frame. So I think an original 1 ton or 1.5 ton frame should be fine.
Here is a video of the one and only time I pulled, not real good quality but the noise is good..
I was in the class called "street legal diesel" mostly new 1 ton 4x4 pickups, no weight restrictions, my truck weighed 10,000 lb.
I'll second OldSub's provide plentiful and good information get better answers. Why don't you sit down and type up what your plans really are? What engine, transmission, rear, will it be driven on the street, how much, what other uses, how much money are you looking to put in it, and anything else important.
