If you've towed a vehicle behind your RV, you may have discovered you have problems with the back bumper and hitch bottoming out in certain situations. If that's the case, you need to install RV skid wheels on your RV. These skid wheels help protect the bumper and undercarriage of your coach and make it easier to tow a vehicle in just about any situation.
You can install RV skid wheels to the bumper with heavy-duty screws, but these can rip off in certain situations. Many RVers prefer weld-on RV skid wheels because they offer more protection in more situations. Most RV dealers carry both types of RV skid wheels. Check with your dealer to see which one they recommend for your RV towing situation.
