I once followed an Exiss out of the parking area (ake hay field) at an event. There was a sizable "lump" that you crossed at an angle to get on the driveway.

I was stunned by how much the trailer flexed as it went over the lump. The two back doors, that were lined up normally, were offset from each other by at least 6 inches as it went over the lump.

Made a note then and there never to use, or allow one of my horses to travel in, one.
