Is there anything I can do to make it easier to tow my RV?

I have the hardest time driving while towing my RV because it always seems to want to sway towards the other lane when it is windy or I am on the highway driving fast. I am wondering if there is anything I can to to maximize sway control so I won’t have to deal with this problem so often. We love to go on trips with the RV, but we hate towing it from place to place because we are always worried something bad is going to happen. I wouldn’t want it to sway so far that it would hit someone else’s car.
