Specifically, your motorhome is non-aerodynamically shaped more or less like a big box of Saltine crackers, with a very high center of gravity.
When a mild crosswind, (or a passing truck's wind), hits the side of your rig as it's traveling down the road, approximately 2,300 pounds of wind energy force is pushing to one side, against the cracker box shaped side.
In a strong crosswind, up to 3,500 pounds of force can immediately and randomly hit the side of your rig, pushing you out of your lane.
In winds over 60mpg you really want to park somewhere protected, (any mobile home park in the midwest will do)! America can then watch the RVs and mobile homes being blown around on the 11 o'clock news.
