I've had a new 2017 TG for a couple of weeks now. I had a FW before. I noticed that the left side of the TG, measured at the left fender is about 5/8" lower than the right side. I'm not amused. I stopped by my dealer and they seemed to be concerned and made an appointment to look at it Wednesday. While I was at the dealer, I asked one of the guys in service if I could measure another trike. He found a tape measure and we checked out a new 2017 TG and a new 2017 FW. On both bikes, the left side was between 1/2" and 9/16" lower than the right side.
He plans to call HD and see what the issue is.
A search of the web for information on this problem leads me to conclude that this is a quality control problem on the part of Harley and that it may or may not be corrected by the dealer. If this is a quality problem that is widespread enough to affect 3 bikes at the same dealer, Harley should be ashamed. $40K plus is too much to pay for junk.
