Chevy has 50 million possible option combinations for 1/2t trucks (just a slight exaggeration.) Those options combined with your GVWR and GCWR decide what you can tow safely and reliably without drama. That is all listed on labels in your glovebox and doorjamb. Check the labels and your owner's manual and that will most likely answer your questions. Without knowing that info, we are all just guessing. You may have huge brakes, 4.56 axles, and auxiliary coolers that can easily handle a 12k# trailer; or you may have a light-duty turd running empty 500# below its GVWR that is at its limit with a full ice chest in the bed. We are all just guessing without that info.
BLT2ski is 100% correct. Just because you don't have a factory trailer brake controller doesn't mean you don't have the factory wiring for one. I've owned six GMT400-GMT900 and every single one came pre-wired. Again it's in the RPO codes on the label. If the wiring is there it is essentially plug-and-play to install one and get it working, and a hard wire controller will be cheaper and work better than wireless. Good luck.
