I would go with the manufacturer's recommendations. Why assume people on this forum know more than the engineers that designed the truck and the engineers that specified the tires? With this litigious society I'm sure their specifications are set with your safety in mind.
Hooking up my 5er does not change front end loading appreciably.
Because engineers very rarely have the final say in an OEM environment. If we did you wouldn't have Ford recommending 26 psi in those Explorers...
Engineers only spec psi based on max GAWRs (note I didn't say GVWR), with a factor of safety built in. In real life, you're rarely at both max F & R GAWR.
One can better the "engineering spec" by measuring the axle weight, and look up the inflation tables from the tire manufacturer.
