Neglecting This Critical RV Metric Could Lead to Costly and Dangerous Consequences on the Road

Whether you’re gearing up for a cross-country adventure or preparing to enjoy a weekend getaway, planning an RV trip comes with responsibilities and challenges that can directly affect your safety and enjoyment on the road. Although most new RV owners focus on things like learning how to drive their rig properly or perfecting the proper technique to successfully tow their trailer, the truth is that many tend to overlook one important factor that can lead to serious (and dangerous) problems: weight management.

After all, understanding and respecting your RV’s weight limits isn’t just a friendly suggestion. It’s an essential part of responsible RV ownership for ensuring safe travels and avoiding things like costly repairs, accidents, or insurance problems.

In fact, according to the RV Safety & Education Foundation, over half of RVs on the road exceed at least one safety rating — typically because owners choose to casually ignore their vehicle’s weight limit. A statistic that’s especially concerning when you consider that the consequences of driving an overweight RV — from blown tires and brake failures to handling problems — don’t just endanger the driver, but also everyone else on the road with them. Even if overweight RVs manage to avoid catastrophic failure, carrying too much weight can still lead to excessive wear and tear on your suspension, frame, and engine. Three things you definitely don’t want to deal with on the road.

In order to travel safely, your RV has specific weight ratings determined by the manufacturer based on what the structure, suspension, and tires can safely handle. You’ll typically find this information on a sticker or plate located somewhere in the driver’s area. Out of all the numbers on it, the most important one to keep an eye on is the Gross Vehicle Weight Rating (GVWR). This represents the maximum weight your RV should reach when fully loaded with people, belongings, water, and fuel.

That said, it’s important you don’t confuse the “dry weight” listed by manufacturers — which only accounts for the empty vehicle with no supplies, passengers, or fluids — with the GVWR. The difference between the “dry weight” and the GVWR is essentially the limit of your cargo carrying capacity, aka how much weight you can add. And, considering water alone can add significant weight (about 8 pounds per gallon), you’ll potentially be looking at an extra 320 pounds (for a 40-gallon freshwater tank) before you’ve even packed a single thing.

Once fully loaded, the most reliable way to figure out your actual RV weight before hitting the road is to use a CAT scale at a truck stop. For a small fee (around $14), you can drive onto the platform, follow the scale’s instructions, and receive a printed report that shows your RV’s current weight. From there, you can compare those numbers to your RV’s ratings to see if you’re within safe limits. If your’re overweight, you’ll need to remove items (and reweigh the vehicle) until you reach a safe weight.
