My feeling is that you have a problem in the trailer, but not the truck. It is quite common for the wiring connectors in the braking system to corrode and cause a loss of voltage and amperage. I'd pull the connectors at the wiring junctions, make sure the wires are clean and twisted tightly, apply dielectric grease and tighten the terminals carefully and tape them so that they don't vibrate loose. If your trailer uses the Scotchlocks, replace with crimp or twist-on wiring nuts. Check the wiring with your voltmeter or test light to see that the magnets are properly energized. That's where I would start.
Of course it's easy enough to test the output of your truck with a voltmeter or even a simple test light. The more brake you apply, the more voltage and the brighter the tester bulb should be.
My Arctic Fox 29-5T fifth wheel is pretty heavy for it's size and I set my ITBC output at 5 and the trailer brakes work just fine.
