how far, how heavy of trailer, etc. matters.
if the '61 is a long wheel base i personally wouldn't pull anything. any torquing of that unibody and i would be afraid of twisting/cracking the body.
i would maybe pull something short distances - if its a short wheel base, around the house but not far.
trucks have a good frame, i would worry more about the body taking it.
I have towed across country several times with my 62. I towed cars and trucks, not trailers. These where full size rigs from the 50's and 60's. Some on an auto transport trailer and most just with a dolly. It has a stock suspension with a 4 point hitch. No trans cooler either and never had a problem other than blowing an exhaust doughnut on a mountain pass at 2 AM. Now that woke up the neighborhood let me tell ya.
Ya say yers is now 4X4 so I figure it wasn't always that way. So me thinks ya have modified the suspension some already. What all have ya done to get that conversion in?
Reason I ask is I am thinking it prolly reinforced it over the stock setup I have.
So with a little heaver shocks your suspension should handle it with no problem.
The only concern I have for you is brakes. Mine are stock drum with no power assist. And an Auto trans. So I used the trans by shifting down to help keep the brakes from fading on the down hill side of the long passes. The C6 is one tough tranny and I had no problems with it.
Whats yer engine and trans combo? And are yer brakes power assisted? Them's the only concerns I would have.

I feel; the towing will no effect the body as bad as one would think; its having weight capacity in the bed that are the faults of uni's. I been told of uni's twisting so much the doors pop open. But straight line towing I can't see where the body factor comes in. I colud be mistaking but who knows until they try. I just recommend a reciver hitch towing not bumper style.
