I have a 2020 Sierra 1500, and just purchased a dump trailer for occasional personal use.

There are general reports (not vehicle specific) of people blowing the charging circuit fuse if they don't unplug dump trailers prior to using the hydraulics. It seems to stem from a low charge on the trailer battery, and then drawing too much current through the tow vehicle charging system when operating the lift.

 

With everything computer controlled in these new vehicles, is there a built in protection from this type of occurrence, where I don't need to be mindful to unplug the trailer prior to operating the dump hydraulics?
