My first thoughts, too - that pin might be fine for a pop-up camper, but....
Well he’s got his chains hooked up, what’s the problem? /s
“I don’t doubt that the Silverado can pull it “
Modern pickups are so much more powerful these days. I do not know about Chevy, but I had a 2011 F150 that put out 360 HP and while hauling a 5,000 lb slide-in pickup camper and pulling our pontoon boat could safely pass other vehicles going up hill. Totally unbelievable.
Our 2018 F150 has 395 HP with a 10 speed with a manual shift option. In manual shift I can floor that thing, work through the gears like a big rig and from a dead stop at a rest area I can be doing 80 by the time I get on the interstate. That’s when hauling that 5,000 lb camper.
So you’re right, for Chevy to be competitive, they must be similar equipped.
This guy has air brakes hooked up, and if the trailer is empty I see no problem.
