Mine is a heavier by like 1000 lbs give or take a few. But does have larger tanks. Loaded im probably about 4900. Not bad. I had a 2012 sierra and tbh wasnt fun towing on long trips i was probably closer to 5400 on that one and had the truck bed full. People say they have no problems towing with a 1500 at like 8000 lbs, my experience was the exact opposite. Especially when entering the hyway or trying to keep speeeds up.
Op, how many people? And what are you towing with? Hybrids are nice also. Mine is an expandable. So it has a rear bed slide. Lots of stuff out there, just have to find the right one at the right price.
