I had a pickup truck that overheated when pulling a load. I installed a bigger radiator in it. Solved the problem.
Another thing to check is the rear end/differential gear ratio. If it has a highway rear end rather than a towing rear end, it causes the engine and transmission to labor more under load. This is particularly rough on an automatic transmission.
