I purchased a pair of wheel locks on ebay they are wood and made to fit your TT. You make a simple adjustment when you get them and they lock in very fast and easy. the ebay number is 330548979321 they stopped all the rocking in my 29N, I do use wood blocks under my flimsey corner jacks and that also helps the settling. Happy camping!
