Obviously, from my signature, you can see what I'm towing with mine. I estimate my total camper weight at around 8700 lbs. The truck is just about to hit 50k miles, with just over 8k hitched.
If you want real towing reviews, try the site below. They load every truck to the maximum weights spec'ed by the manufacturer, then run Ike's Gauntlet on cruise control and time them through the course, along with fuel mileage, brake temps, etc. It's the most thorough, objective analysis that I've seen.
Oh, one note on reliability ... I've spent many more repair trips and a lot more money on the camper in the 3 years that I've owned it, than the truck in the same period. 😀
