The guy that does my exhaust work was a dirt track racer up into the 90s. He used a stock '51 Chevy 1/2 ton with a scratch built receiver hitch to pull his car and trailer to the races. the closest rack is 30 miles away.
I installed a hitch from TBRT Engineering on my daily/only driver '53 GMC and used it two or three days later to haul this -

The picture is misleading because of the way the truck is parked on the hill, on flat ground it only squatted the rear about 1 1/2 inches. I hauled the truck 20+ miles at 55-60 miles an hour on hilly, curvy roads and it handled great. Of course all bushings and shackles are new as well as the entire stock brake system.
I don't plan to haul anything like this again, ever, but my point is, the truck, even with its 63 year old stock suspension, handled this load like it was built for it.
A 1000 lbs trailer will affect acceleration and braking a bit, but it should handle fine.
