The heavier Toyota might control the slightly lighter mass of the trailer in gusty winds better than a lighter than trailer weight vehicle. I would consider the tow vehicle with the widest stance for stability from side loads imposed by the trailer connection.
Since pickups have relatively light loading on the rear wheels to be able to carry cargo, one might be wise to carry spare water or the like in addition to the tongue weight so the rear tires get a good grip on the road.
