Living in Los Angeles I would not use a synthetic blend. The advantages with the 5w40 oil is when driving in sub-zero weather. Not a lot of that in So CA. The downside of these oils is polymer shearing which translates into less protection for the engine's main bearings.
Towing or heavy hauling transates into severe duty and per the manufacturer's recommendations I change the oil and filter more often than if the truck was used to commute to work each day. With a 5k oil change interval there is zero benefit to use a synthetic over a SAE grade mineral oil.
If synthetics lived up to the hype it would be used in every big rig on the highway and every taxi cab in the world and it is not being done.
