How Much Does a Trailer Weigh? | I Heart RVing

Knowing how much a trailer weighs is critical to making the right purchase decision when buying a camper. Relatively few passenger vehicles can safely tow a 24-foot trailer or longer, and knowing your travel trailer weight is essential to selecting the right hitch and staying within your towing capacity. Knowing the basics makes you more confident at the dealership and helps you choose the perfect travel trailer for your needs.

The Importance of Knowing Trailer and Camper Weights 

It’s impossible to overstate the importance of knowing trailer weights from a safety standpoint. Exceeding your towing capacity strains your vehicle’s engine, transmission, brakes and axles. What’s even worse is you could lose control, causing a serious accident. Trailer swaying, mechanical failures or an inability to brake result from attempting to tow too much and can lead to disasters on the roadways. 

Deciphering Weight Metrics for Trailers and Campers 

You’ll need to know several weight metrics for trailers and campers — and your tow vehicle — when selecting the best one for your needs. There are several terms you must understand, including: 

• Payload capacity: The maximum weight you can add to your tow vehicle’s cargo area. 
• Towing capacity: The maximum amount you can tow after factoring in the weight of the tow vehicle and any cargo. 
• Gross vehicle weight rating or GVWR: The weight of your tow vehicle, plus passengers and cargo.
• Gross combined weight rating or GCWR: The weight of your tow vehicle with the trailer attached, including passengers and cargo. 
• Tongue weight: The downward force applied to your hitch when connecting your trailer for towing. 

Most experts recommend staying within 80% of your GCWR. That means doing a bit of math. You must calculate the rough weight of your passengers and cargo plus the weight of your tow vehicle and trailer, subtracting 20% from that number to find your max. 

When buying a trailer, you’re generally safe if you stay within 75 to 80% of your tow vehicle’s towing capacity. However, remember the other factors. If you typically carry a quad or canoes in your truck bed when camping or traveling with multiple passengers, you might need to get out the calculator. 

Factors That Affect Your Trailer’s Weight

Factors affecting weight typically stem from the options you select during purchase. Upgrading your camper after you buy it also impacts it. Basically, you should consider the impact of any modifications on your travel trailer’s weight. 

For example, a basic aluminum teardrop trailer with no plumbing or wiring may weigh less than 2,000 pounds and be light enough to tow with a motorcycle. However, larger models with more amenities can weigh several times more. 

Your trailer’s plumbing is one of the most crucial factors affecting its weight, as each gallon weighs just over eight pounds, plus the weight of the equipment. Please keep in mind that towing with empty tanks isn’t always an option. For example, boondockers must arrive with full freshwater tanks and carry their gray and blackwater to an approved dumping location. Consider the weight of the tanks when full when making your purchasing decisions. 

Other upgrades have a less noticeable effect, but you must still calculate their weights when upgrading. Heftier accessories, such as solar panels, an external generator or appliances like a stove, require you to get out the calculator to ensure you aren’t approaching the 80% mark of your GCWR. Smaller improvements, such as adding acoustic foam or RoadBlockR for soundproofing, blackout curtains for privacy or a thicker replacement mattress, may not require math unless you know you are close to that magic number. 

Comprehensive Weight Breakdown by Trailer and Camper Types 

Trailers and campers come in various shapes and sizes, from tow-behind pop-ups to luxurious fifth wheels. While you must always work with your dealer on the stats for specifics on how much your trailer models weigh, here are some general guidelines: 

• • Most teardrop and small, un-outfitted enclosed trailers and pop-ups range between 500 and 3000 pounds. 
  • Small travel trailers, such as the Airstream Bambi or Forest River Wolf Pup weigh 5,000 pounds or less, suitable for towing with many half-ton SUVs. 
  • Your standard 24-foot trailer or toy hauler averages around 5,000 to 7,000 pounds, although the weight may vary depending on what you stow inside. 
  • Models larger than 24-foot trailers, such as fifth wheels, may weigh anywhere from 5,000 to 20,000 pounds and typically require a 1-ton truck with adequate bed space for the unique tow hitch. 

In general, it’s best to tow anything larger than a 24-foot trailer with a 1-ton or larger truck to prevent damage to your vehicle. Towing capacities vary, so know your truck and work with your dealer. 

When purchasing the right camper or trailer weight for your needs, you’ll also need the correct hitch. Your trailer tongue weight compresses this connection point, and the wrong can lift your vehicle’s front axle. This dangerous condition can result in a loss of vehicle control and insufficient braking power, which can lead to an accident. Speak with your dealer about the correct hitch and take your tow vehicle to the dealership for installation if unsure. 

Another must-have for many trailers with significant weight is a separate electric braking system. If your trailer is too heavy, it can surpass your tow vehicle’s capacity to stop, especially when descending steep hills. In most jurisdictions, trailers heavier than 3,000 pounds require a separate electric brake system. Most also require automatic deployment if the trailer becomes detached from the tow vehicle, but rules vary from place to place — check your state’s Department of Transportation. 

Choosing the Right Trailer or Camper Weight for Your Needs 

Understanding how much your trailer weighs and its impact on your tow vehicle is crucial to staying safe on the road. Even small trailers can cause accidents. Knowing how much you can safely tow protects you and other drivers while preventing unnecessary wear and tear on your car or truck. Use this guide to select the right camper or trailer weight for your needs.
