Hitch for a Pop Up Camper

HI,
I am new to the Trailer towing world, I am going to be purchasing a pop up camper very soon, I just have a couple of questions. I already have a towing package in my truck ( 2015 Chevy Silverado 1500) I am not too sure which hitch to buy? do I need a weight distribution? and also do I need sway bars? Any feed back would be great

Thanks
J
