How much does the length of a TT affect driving?

We are close to 60ft when hooked up. I've never had an issue anywhere. I fuel up at regular gas stations because I don't like truck stops. I work in a city in which I patrol two truck stops and the issues we have there aren't what I would like to expose my family too while traveling. Get the Floorplan you like and don't worry about length. It's not a problem
