1/2 ton towable toy haulers

This has been a great camper but currently looking for something little bigger but also want to stay with the current truck. I am also Leary of the manufacturer reporting the bigger ones I'm looking at are half ton towable.

Towed my 28ft toy hauler (7800lbs dry) home with my half ton Chevy then immediately went shopping for a bigger truck.

I know this is bigger than what the op is asking about but this is my current setup and my family and I love it!
