i dont think so..that would be like saying youd avoid every vehicle made by FCA after they had a huge airbag recall. I would ensure that anything you buy is in good order at the time of purchase, you have a warranty if possible, its registered with the manufacturer if thats an option, you followed scheduled maintenance suggested by the manufacturer, and be fastidious about the upkeep of the TT. Id also be sure that frame damage is covered by your insurance company..and under what circumstances it is and isnt.
you can do a little googlein' on how frames get damaged and after watching a few videos, and getting over the knee jerk reaction of they all break, youll start to see the common factors in frame damage and know to avoid them. for instance When I am in a campe ground I try to walk a good portion of the route to my site before driving it. If there is a substantial change in grade I will unhook my WDH to avoid it putting extra strain on the A frame when possible. Does it help...who knows. But I certainly feel like it does haha
