I recently had to tow a non-running Ford Ranger to a buyer about 45 minutes away from me. My car trailer has an empty weight of 1,600lbs, and the curb weight of the Ranger is just shy of 3,000lbs, so coming in at 4,600lbs total (give or take), which is still a little under the advertised max. Let me tell you right up front, I will never haul that much weight with the Telluride again. It struggled so much more than it should have, especially going up normal sized hills (for Pennsylvania), and holding onto 1st, 2nd and 3rd gears until 5,000rpm or more. I know it won't take too much of this kind of towing before things start breaking, or wearing out at an accelerated rate. One of the main buying points for us was to have something to haul the family around AND to haul my Nova to car shows and cruises that were hours away. I know without a doubt right now that these Tellurides were not made to haul 5,000lb every weekend in the summer. Maybe a few times in their life, in a pinch, but that's it. It has been hauling our approx. 3,300lb pontoon around fairly decently, although it does tend to drag out gears a little more than I'd like (towing mode isn't a driving option of course - since I don't think that it was ever designed around towing specifically). We'll probably be listing it for sale over the winter and just get an Expedition with the EcoBoost engine or a Suburban, or something more capable of towing. Such a shame though. My wife loves the Telluride otherwise (although I have reservations about a half dozen other things I don't like about it, other than looks), so she is hesitant to sell it, but we can't afford to have a different vehicle for each different activity we want to be involved in...
