Hey NinjaGrunt, I've never had the opportunity to tow with either of these vehicles as of yet. Not sure about other years but my 2012s both had towing packages from factory that I insisted on for one main reason. Full sized spare tire INSIDE NOT UNDER THE VEHICLE was standard with the package. My last AWD vehicle before this was a joke. They gave me a doughnut under the vehicle that could not be used 25 MPH or limited distance. I read later that anyone who installed that tire couldn't drive at all because the different sized diameter tire threw the AWD system and computer shutting down the car. I might be wrong but it leads me to believe that many manufacturers might be eliminating spare tires for that reason and not for saving gas as some salesman try to convince me. For years they've told us don't put fix a flat in tires because its bad, now its the perfect replacement for a smaller diameter tire when most cars are AWD. ????????
To get back to towing question, The overland has air lift suspension, the other vehicle has standard. The towing package on the standard suspension came with special self leveling shocks. Not air shocks but self leveling hydraulic. THOSE ARE STILL THE LITTLE QUIRK I MENTIONED EARLIER! I had those expensive shocks replaced several times under warranty. They have been making noise as always ever since the warranty ran out. They get a little intermittent, fluttery, or clunking noise if its quiet in the car wile you drive over wavy roads. It went away every time they replaced them but returned again around 8 to 10 thousand miles each time. "It sounds like its in the spare tire compartment, but is still there if you remove everything in it". I've read about this on other forums and it was a known issue back then. Not sure if these shocks even offered on newer models or if they still exist. I was told by dealer back then they were German manufactured parts from the Daimler design. Anyway I also read that some people like me had the dealer replace them with standard shocks under warranty and they would only if you signed a waiver.
I cant speak of the curb weight or limits. I'm sure its listed online. Believe me I've towed lots of things with older full sized trucks of multiple brands with V8s. They didn't have half the HP or pick up of this V6. I would say no problem to anything reasonably sized!
