Knowing precisely how to measure your camper trailer is crucial for everything from storage and campsite selection to legal compliance and ensuring compatibility with tow vehicles. Accurate measurements allow you to confidently navigate the world of RVing and avoid costly mistakes.
Why Accurate Measurements Matter
Precise camper trailer measurements are paramount for several reasons. First and foremost, they ensure safe and legal towing. Exceeding height or width restrictions can lead to hefty fines and dangerous driving conditions. Secondly, measurements dictate where you can store your trailer, both at home and on the road. Overestimating or underestimating can result in storage nightmares and damaged property. Finally, accurate dimensions are essential when booking campsites; squeezing a trailer that’s too long into a too-short space is a recipe for frustration. Measuring correctly is not just about numbers; it’s about safety, convenience, and peace of mind.
Essential Measurements to Capture
To effectively measure your camper trailer, you’ll need a reliable measuring tape (preferably a long one), a helper (for easier and more accurate readings), and a level surface. Ensure the trailer is parked on level ground and that the tires are properly inflated.
Length: Hitch to Bumper
The overall length is the most commonly requested measurement, and it’s usually what manufacturers specify in their brochures. This measurement includes everything from the tip of the hitch to the rearmost point of the bumper or spare tire, whichever extends further. Don’t underestimate the importance of this figure; campsites and storage facilities often use overall length to determine pricing and availability.
To obtain this measurement:
- Start at the outermost point of the hitch.
- Extend the measuring tape to the outermost point of the bumper, spare tire, or anything else protruding from the rear.
- Record the measurement.
Width: Widest Point to Widest Point
Width is another critical dimension, often overlooked but essential for navigating narrow roads and fitting into campsites. Measure from the widest point on one side to the widest point on the other, including awning hardware, ladders, or any other protrusions. Remember to account for mirrors, if applicable (though these are often removable for storage and should be noted separately if permanently attached).
To obtain this measurement:
- Identify the widest point on one side of the trailer (e.g., awning hardware, a ladder).
- Extend the measuring tape horizontally to the widest point on the opposite side.
- Record the measurement.
Height: Ground to Highest Point
Height is crucial for clearing bridges, overpasses, and low-hanging branches. Measure from the ground to the highest point of the camper, which might be an air conditioning unit, a vent, or a satellite dish. Make sure to measure with the tires properly inflated and the trailer level. It’s better to overestimate slightly than to underestimate and risk damaging your trailer.
To obtain this measurement:
- Find the highest point on the trailer (e.g., air conditioner, antenna).
- Use a straight edge (like a long level) extending out horizontally from the highest point.
- Measure from the ground to the straight edge.
- Record the measurement.
Interior Dimensions (Optional, but Useful)
While not always necessary, knowing the interior dimensions of your camper can be helpful when planning storage solutions, purchasing furniture, or simply maximizing usable space. Measure the length, width, and height of the interior living area at its most expansive points. Note any obstructions or areas with reduced headroom.
Additional Considerations
- Awnings and Slide-Outs: When measuring width, be sure to specify whether the measurement includes awnings or slide-outs extended. This is important for campsite selection.
- Weight: While not a measurement of size, Gross Vehicle Weight Rating (GVWR) and dry weight are critical for ensuring your tow vehicle can safely handle the trailer. Check the manufacturer’s specifications for these values.
- Documentation: Keep a written record of all measurements, including the date they were taken. This documentation can be invaluable for insurance purposes or when selling the trailer.
- Double-Check: Always double-check your measurements! A small error can have significant consequences.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions about measuring camper trailers:
FAQ 1: Where can I find the official dimensions of my camper trailer?
Most manufacturers include the official dimensions in the owner’s manual or on a sticker located inside a cabinet or near the entrance. However, it’s always a good idea to verify these measurements yourself, as discrepancies can occur.
FAQ 2: Do I need to measure my camper trailer if I already have the manufacturer’s specifications?
Yes! While the manufacturer’s specifications are a good starting point, they might not reflect modifications or additions you’ve made to the trailer, such as a roof rack or a different type of spare tire mount. Always verify the measurements yourself to ensure accuracy.
FAQ 3: What’s the difference between overall length and box length?
Overall length includes the hitch and bumper, while box length refers to the length of the living area itself. Campsites and storage facilities typically ask for overall length.
FAQ 4: How important is it to measure the height of my camper trailer?
Measuring the height is extremely important for avoiding collisions with low bridges, overpasses, and tree branches. Underestimating the height can result in significant damage to your trailer.
FAQ 5: What’s the best way to measure the height of a tall camper trailer?
For tall trailers, consider using a laser measuring tool or a long pole with clearly marked increments. If using a pole, ensure it’s perfectly vertical and supported. Having a second person help is highly recommended.
FAQ 6: Should I measure my camper trailer with the awning extended?
Only if you plan to travel with the awning extended (which is generally not recommended). Otherwise, measure the width with the awning retracted. Be prepared to specify the width with the awning extended when booking campsites.
FAQ 7: What happens if my camper trailer is slightly larger than the campsite dimensions?
Contact the campground before your arrival. Some campgrounds may be able to accommodate slight overages, while others have strict size limits. It’s better to know in advance than to arrive and be turned away.
FAQ 8: How do I account for modifications when measuring my camper trailer?
Carefully consider any modifications you’ve made, such as roof racks, solar panels, or different tire sizes. These modifications can alter the height, width, and length of your trailer, so be sure to include them in your measurements.
FAQ 9: Why is knowing the weight of my camper trailer so crucial?
Knowing the weight, specifically the GVWR (Gross Vehicle Weight Rating), is essential for ensuring your tow vehicle is capable of safely towing the trailer. Exceeding the tow vehicle’s capacity can lead to serious accidents and damage.
FAQ 10: Where can I find the GVWR of my camper trailer?
The GVWR is typically found on a sticker or plate located on the trailer’s frame or near the entrance. It’s also usually listed in the owner’s manual.
FAQ 11: What tools do I need to measure a camper trailer accurately?
Essential tools include a long measuring tape (at least 25 feet), a level, a helper, and a notepad and pen for recording measurements. A laser measuring tool can also be helpful for measuring height.
FAQ 12: Can I rely on online databases for camper trailer dimensions?
While online databases can provide a general idea, they may not be entirely accurate. It’s always best to measure your own trailer to ensure the dimensions are correct, especially if you’ve made any modifications.
