Thank youI haven’t towed my pup yet with the telluride, but if it ends up anything like the Sienna, I will add air bags to the rear springs to help with sag. Mine is a good bit less than yours (2700 lbs loaded weight, about 330 lb tongue weight). You will probably be in the 400 lbs or so tongue weight (just a guess). So without the self leveling suspension, I would expect you would need to do something about rear end sag. Again, this is coming from someone who hasn’t towed anything in the telluride yet.
