Help requested for first time rv trailer buyer

Some bumpers are good to 5,000 lbs. Many states do not require brakes under 3,000 lbs. if your state and truck meet this then it should work. Many pop ups are towed on bumpers. Once loaded the trailer will go over 3,000 so be sure it is empty. As for towing once you are caming then the full hitch and brakes will be needed. Your truck will need more than a 4 prong wire fore the brake controller to work. Good luck.
