Longer wheel bases on motorhomes and trucks towing RV trailers make it necessary to change your turning patterns. You must turn wider at intersections or the rear wheel may roll over the curb. Go further into the intersection before starting the turn and adjust your lane position to increase the turning radius.
Curves in the highway can also be tricky. Stay more to the center of the lane for right turns so the rear wheels will not move off the pavement. For a left turn or curve, stay more to the right of the lane to prevent the back of the trailer from tracking into the oncoming lane
Recreational vehicles have a high center of gravity, so turning corners and taking curves must be done at slower speeds to prevent swaying. Slowdown before you enter the curve. Be sure you use your rear-view mirrors to watch tracking and tail swing.
