Thanks for the quick response, i had not considered that it could help stiffen the car's unibody. Yes, eTrailer offers BOTH the EZ4 and the EZ5 for the Kia Soul. I would prefer to not have the extra part if I don't absolutely need it, but if it keeps the car from wandering around, no doubt I will go for it. I am trying to get my mind around the physics though, I guess in a turn or sharp turn it may help, but pulling straight down the highway it would not make a difference.... I think...????
