All campers are heavier than you think/ are advertised. Trucks generally have a lot less payload than you thing / are advertised. Making a TC work on a 1500 is tough. Your 2wd so that helps on the weight some. If it's just you and you pack light you can probably make it work.
Have you weighed your truck? I'd load it with the people, pets, fuel, etc. you'll be carrying with the camper. Remove the tailgate and weigh it on a scale. Pay particular attention to the rear axle weight. That's the only way to know how heavy of a camper you can haul.
