Everyone is different in what they are comfortable with. I had a 2013 Silverado extended cab 4x4 with a fiberglass cap, pulling 5,000 lb TT. The bed was loaded and the rear axle was right at max capacity of 1,650.
It was about all the weight I would want to pull with that truck. It would get up and go when entering the freeway and was able to pass when needed and I wasn't worn out at the end of the day. It wasn't like there was nothing back there either, it was noticeable. It had a wdh and sway control. If you are staying real close to home it may work and then go with a 3/4 ton down the road.
It will do it but you will may get tired of it.
