We have a Jayco Jay Flight 28BHBE with 2 teenagers. We pull it w/ a 2012 burb 1500. I haven't had us weighed yet, but I feel we are at our max. We don't put anything but phone new and a drink cooler in the burb. We travel dry also. The burb does a good job, but I'm not going up any mountains, just central/eastern NC. But we did a trip to Disney last summer w/ no problems. My biggest concern ncern was transmission temps, but even w/ 103 outside temp trans temp only got to 216 I believe.
Yes, I want to upgrade to a 3/4 ton, but for now it works. I air up all tires to the max recommended pressure and it helps a lot.
