Longer wheelbase on the towing vehicle with a robust suspension.

Perhaps an even more important metric is the ratio between the wheelbase and the distance from the rear axle to the hitch ball. Long wheelbase with the hitch close to the axle is best. Short wheelbase with long distance between the rear axle and hitch gives the trailer more leverage over the car, and the car less leverage against the ground to resist lateral disruption.
