I have a 2017 Silverado 1500 LT, Crew Cab Short Bed, 4x4 with 5.3L and 3.42 gears. The truck's placarded payload is 1702, GVWR is 7200, GAWRF and GAWRR are both 3950, rated tow capacity is 9100, GCWR is 15,000.
I have a 2018 Wildwood X-Lite 282QBXL, which is 32.5' long from tongue to spare tire. The 282QBXL has a placarded 6052 dry weight with a 626 spec tongue weight, and a GVWR of 7636.
The truck pulls the trailer with absolutely ZERO issues running 70mph on the interstate, and IIRC I'm turning about 2700rpm at that speed. Like most wind sails, the trailer can get blown around a bit when its gusty but I haven't really experienced the "sucked in by semis" that some folks talk about. Pulling a long, decent grade hill I do get RPMs up around 4k to maintain 70mph, but its a naturally aspirated V8 and that's where the torque is so no big deal. Running 70mph I average about 10.5mpg while towing.
Weigh slip is truck, full tank of gas, me, weight distributing hitch, trailer, battery, two full propane tanks and 2/3 fresh water tank. PLENTY of margin for my wife, two kids, and stuff.
