A very significant factor, mentioned by Bob above, is the vehicle and the quality of suspension and tires on the vehicle.

Generally said, a vehicle that handles very well, with good tires properly inflated, should be a decent tow machine.

It is important to not have the trailer tail heavy, but over loading the tongue on a bad vehicle- trailer combination won't solve much and can make a poor combination worse. Old tires and suspension, with low air pressures, and maybe some extra overhang on the tow hitch,and a really heavy tongue, will make a very uncomfortable situation.

Moving some heavy crap out of the trailer and into the tow vehicle, between the axles can make startling improvement in some cases.

Jaguar XJ6 towing Cobra trailer, is the best combination I ever used. Solid, comfortable, and safe at any speed you would want to drive the car. But not a desert rig. Never had more than 75 lb on the tongue.

Quick and timely corroboration of the above. I sold my LS8 with 1990 Komet Euro Light trailer last week. Incredibly well behaved rig behind anything that's towed it over the last 14 years (Sprinter Van, Honda Odyssey, VW Sportwagen TDI). New buyer got only a few miles down the road on Interstate 95 before calling to ask about significant sway at highway speeds. What changed: 1) the tow vehicle 2) I took out a bunch of crap from the front of the trailer.

New buyer was towing with a Toyota Tacoma. The first/easiest thing to do was to up the tire pressure in the rear of the Tacoma to max recommended pressure. Calls back one hour later to report that everything is great. A simple fix with positive results.

FWIW, I've always towed with the rear tires at their max recommended pressure in the tow vehicle. Has worked well for me over the years.
