When you start driving a motor home, you will be quick to find that it is not a sports car. You are driving a house, fully equipped with furniture, personal items, dishes, glasses, packaged foods, and liquids. Unless you have someone standing in the aisle to catch things, you will find that jack-rabbit starts and hard braking are not really smart things to do. And you will learn to allow plenty of room around your rig to prevent sudden changes or rapid movements. And all of that stuff really needs to be secured as much as possible. The same applies even more so to a trailer behind you.
