Are there any Model X owners with a towing package equipped vehicle in the Colorado area? Or owners willing to road trip there? The reason I ask, is because it would be great if you could team up with the guys from The Fast Lane Truck to have them do a towing review. Towing reviews are their specialty. They use the steepest part of I-70 in Colorado and tow trailers that are right at the max of what vehicles are rated to tow. They also descend the mountain so it would be interesting to see how regen braking keeps a 5,000lb trailer under control. Link to their site, you can contact them through it if interested: http://www.tfltruck.com/tfltruck-hall-ike-gauntlet/ I feel like this would answer a lot of questions we all have about the true towing abilities of the X.
