One thing to know about RV manufacturing is that the components are designed to be as light as possible in order to reduce weight. This means that they are not always made from the most solid of materials. So, whether you’re buying a new or used RV, you need to a do a thorough inspection before you hand over your hard-earned money. New or used, signs of interior moisture are the biggest red flags to look for when buying an RV. Check the interior with a moisture meter. Anything above 20 percent means there is a problem that needs attention. Look for signs of water damage or mold. Look for damage to floors. Bounce up and down in the kitchen, bathroom, or anywhere near water to check for soft spots. Inspect the exterior for damage, especially around window and door frames and vents. Always check the tires to make sure they are currently serviceable. Use the VIN number to get the vehicle’s history to see if it’s ever been involved in an accident. Finally, always try and buy from a reputable RV dealer, as they will often have the ability to fix any problems—or agree to do so—before you sign on the dotted line.
