You are going to need a bigger truck. Towing capacity is not your issue, payload capacity is. Even the lightest pop ups are right at the edge of your payload capacity. Half tons can carry a light camper or pull a boat, but doing both is a bad idea. I went though the exact consideration a few years ago. By the time you do all the necessary upgrades to your truck to get it to carry a camper (tires, shocks, airbags, etc), you could have a nice down payment on a 3/4 ton.
I have a Northstar 650 and it is well built. It is an extreme improvement over sketchy motels. Mine is only 7 feet wide, so I can see both sides of the boat while towing and launching. Lots of campers are 8 feet wide, and you will have a hard time seeing your boat. PM me if you have any questions.
