Wanted to share this pic of the LX470 loaded up for a track day today. The LX made this trip smoothly and in great comfort. It was nice heading out to the track day knowing that I had a guaranteed ride home no matter how hard I beat my other car on the track. 
This combo weight was 2100lbs trailer + ~3400lbs car for a grand total of 5500 lbs. Cruising on the fwy was easy. I could hold 70mph up most any hill that I wanted to. The truck was never pushed or swayed by the rear load. Super stable. Can't imagine the max rating is 6500 when this load was so effortless.
