Travel Trailer Tilt

Thanks everyone for your input. I'm not sure about the 3" measurement. All I know is the Truck is level since it's still on the street and the camper while backing in to my driveway is at a 15-20 degree tilt for those 30 feet until the two passenger side wheels get on the driveway. There are no sharp edges. it's a blacktop street and driveway so the edges are rounded over. We don't store it there but use the driveway to pack/unpack for trips so it's not such a long haul back and forth from our designated pad.
