There's a youtube channel (the fast lane truck) that did a comparison between the TC, the promaster city and the nv200 and also a towing test (ike gauntlet) with the promaster city.
I posted a comment under the towing video and I also sent them an email. Both asking for a towing test with the TC - no answer both times.
Anyone willing to do the same?
My thinking is that if more people request it, they're either going to do it or at least give a reason why they don't.
