The first time we towed our 2012 GMC Terrain it scared me to death on I75 with the sway. It has gotten better with all that we've done to improve things. each step is less & less sway. Why did it sway, I have no idea, I have found nothing wrong. Dealer is no help, they say never heard of tail wag while towing. We have adj tire pressure, alignment, added 4" drop rcv to make it level, HD steering stabilizer, Tiger Trak bar and now finally 1 1/2" sway bar. This was all done to a new 2014 Thor 22E Chateau. That's it, I will do no more to this coach.
