Notice height restriction signs on bridges, gas station canopies and other structures. Keep an eye out for low-hanging branches over the road. Check the owner's manual or ask the rental company for maximum height information on your particular RV.
Know the length of your RV and avoid roads that restrict the operation of vehicles over a certain size. Allow for the extra length when parking, changing lanes, passing vehicles and merging onto a freeway.
Anticipate a longer braking distance with the heavier vehicle. When traveling on a long downhill grade, use lower gears to prevent the brakes from overheating.
Practice good manners when you are moving slower than the speed of traffic. Keep in the right lane on multi-lane highways. Pull over on an uphill climb when five or move vehicles are lined up behind you wanting to pass. When traveling in a caravan, leave enough room between vehicles to allow cars to safely pass each RV.
Check that your RV has the necessary power before attempting to tow a car, especially on an uphill grade. Also test the braking capability with the added weight of a car in tow.
