I just got back from my 1st towing experience with this vehicle:
Mastercraft ProStar. Somewhere in the 2000+ range (not sure), but the tank was empty.
Anyways, I was really impressed with how well she did, especially going over the mountains. I had previously pulled it with a v6 Land Cruiser and this v8 engine had NO trouble getting up those hills at 75 mph. My brakes are coming up on 30k, so I was pretty careful on the downhills, but everything felt great.
Anyways, just wanted to share that with any prospective 4th gen owners...towing is a no-brainer with the v8.
