If you are towing a trailer, there is a maximum of only about 20 amps leaving the Truck towards the trailer for charging it's battery, and perhaps another 20 amps for lights and such.
The brakes can use 20 - 30 amps (two or three axle) at the very most, with oversized #10 gauge wire, but it is such a short term - only 10 - 20 seconds during a 10 minute drive.
A normal 100 - 130 amp alternator can run everything on the trailer. Unless you upgrade the wiring between the trailer to say #8 wire, then it might possibly carry as much as 30 amps.
It would be better to install a solar system on the trailer, and not worry about how many amps the engine puts out.

$229 will buy a 140 watt solar panel with a aluminum frame. 6" long 2" angle aluminum will make mounts for the roof. UV rated direct burial romex is rated for the sun, rain, and snow!
