I pulled a 3700lb camper with mine back in 2021. Bone stock, only thing I changed was I filled up with 91 instead of my usual 87. I also picked up a Kurt wireless/bluetooth brake controller, which worked fairly well overall minus a glitch or two. I ran in towing mode, and other than a bit of clunking from the hitch it was pretty smooth sailing and it didn’t struggle with the added load at all. The worst I could say is that the back end squatted a bit more than I would have liked, but I didn’t use a WDH nor do I have airbags, so I just accepted it as unavoidable for that one instance.
