Why Accurate RV Measurements Matter

Getting the right size RV cover is crucial for several reasons:

• Protection: A well-fitted cover protects your travel trailer from sun damage, rain, snow, dust, and debris.
• Longevity: It extends the lifespan of your RV by preventing premature wear and tear.
• Proper Fit: A cover that’s too large can flap in the wind, causing damage to the cover and your RV. A cover that’s too small won’t provide adequate protection.
• Ease of Use: A correctly sized cover is easier to install and remove.

Step-by-Step Guide: Calculating Trailer Cover Dimensions

Before you start, gather these tools:

• Measuring tape (at least 25 feet long)
• Ladder (if necessary)
• Pen and paper
• Helper (optional, but recommended)

Step 1: Determining Travel Trailer Length Measurement

The most important measurement is the length. Follow these steps:

1. Start Point: Begin measuring from the longest point at the front of the trailer, usually the front of the hitch or the front cap.
2. End Point: Measure to the longest point at the rear of the trailer, typically the bumper or spare tire (if mounted externally).
3. Exclusions: Do NOT include the following in your travel trailer length measurement:
   • Hitch
   • Propane tanks
   • Ladders
   • Bumpers (unless permanently part of the trailer’s structure)
4. Record: Write down the measurement in feet and inches. Round up to the nearest foot.

Why Exclude Those Parts?

RV covers are designed to fit the main body of the trailer. Including these protruding parts can lead to the cover being too large and not fitting snugly.

Step 2: Measuring RV Height for Cover

Next, measure the height. Here’s how:

1. Ground to Highest Point: Measure from the ground to the highest point on your RV roof. This could be an air conditioner, vent, or antenna.
2. Antenna Considerations: If your antenna is retractable, measure with it retracted. If it’s not retractable, you may need to purchase a cover designed to accommodate it, or consider removing it before covering.
3. Record: Write down the measurement in feet and inches. Round up to the nearest foot.

Important Height Note:

The height measurement is critical. Too short and the cover won’t fit over the roof accessories. Too tall and it might flap around.

Step 3: Measuring Travel Trailer Width

Measure the width of your travel trailer at its widest point. This is usually from the outside of one sidewall to the outside of the other. Most travel trailers have a standard width of 8 feet. However, some may be wider due to awnings or slide-outs.

1. Slide-outs: Make sure all slide-outs are retracted when measuring the width.
2. Awnings: Awnings usually do not need to be included unless they significantly protrude when retracted.
3. Record: Write down the measurement in feet and inches. Round up to the nearest foot.

Step 4: Measuring Travel Trailer Roof for Cover (Optional)

While the overall height measurement usually suffices, measuring the roof separately can be helpful, especially if you have unique roof features.

1. Front to Back: Measure the length of the roof from front to back.
2. Side to Side: Measure the width of the roof from side to side.
3. Note Obstructions: Note the location and height of any roof-mounted accessories.

Why measure the roof separately? This step can help you better visualize how the cover will fit and identify potential problem areas.

RV Cover Sizing Guide: Travel Trailer Cover Size Chart

Once you have your measurements, consult a travel trailer cover size chart provided by the cover manufacturer. Here’s a general example:

Trailer Length (Feet)	Cover Size (Feet)
18-20	20-22
20-22	22-24
22-24	24-26
24-26	26-28
26-28	28-30
28-30	30-32
30-32	32-34
32-34	34-36

Important: Always refer to the manufacturer’s specific travel trailer cover size chart. Sizes can vary between brands. When in doubt, it’s generally better to round up to the next size.

RV Cover Measurement Tips for Success

Here are some RV cover measurement tips to ensure accurate RV measurements for cover:

• Measure Twice, Cut Once: Double-check all measurements to avoid errors.
• Use a Helper: Having someone assist you can make the process easier and more accurate.
• Level Ground: Ensure your RV is parked on level ground when measuring.
• Consider Clearance: If you plan to store your RV in an area with low-hanging branches or other obstructions, factor that into your height measurement.
• Account for Accessories: While you typically exclude propane tanks, consider whether you want the cover to accommodate them. If so, factor in their dimensions.
• Read Reviews: Before buying, read reviews from other RV owners about the fit and quality of the cover.

Special Cases: How to Measure Camper for Cover with Unique Features

Some travel trailers have unique features that require special attention when measuring how to measure camper for cover:

• Slide-outs: As mentioned, retract slide-outs before measuring. Consider purchasing a cover specifically designed for RVs with slide-outs if you want additional protection when the slide-outs are extended.
• Rear Ladders: Most covers are not designed to accommodate rear ladders. You may need to purchase a ladder cover or remove the ladder before covering.
• Spare Tire: Most covers can accommodate a rear-mounted spare tire, but ensure the cover has enough give.
• Awnings: While typically excluded, particularly large awnings may require you to size up your cover.

Problem-Solving Measurement Challenges

What if you encounter a measuring challenge?

• Uneven Roof: If your roof has significant variations in height, take multiple measurements and use the highest point.
• Unclear Boundaries: If you’re unsure where to start or stop measuring, consult the manufacturer’s instructions or contact their customer support.
• Limited Access: If you can’t easily access certain areas, use a ladder or ask for assistance.

Choosing the Right RV Cover Material

Besides size, the material of your RV cover is crucial. Common materials include:

• Polypropylene: Lightweight, breathable, and water-resistant. Good for moderate climates.
• Polyethylene: More durable and waterproof than polypropylene. Suitable for harsher climates.
• Polyester: Offers good UV protection and is relatively strong.
• Multi-Layered Materials: Offer the best combination of breathability, water resistance, and UV protection.

Material Comparison Table:

Material	Breathability	Water Resistance	UV Protection	Durability	Best For
Polypropylene	High	Moderate	Moderate	Moderate	Moderate climates
Polyethylene	Low	High	Moderate	High	Harsh climates
Polyester	Moderate	Moderate	High	Moderate	Sunny climates
Multi-Layered	High	High	High	High	All climates

Installing Your Travel Trailer Cover

Once you have the right size and material, follow these steps to install your RV cover:

1. Clean Your RV: Remove any dirt, debris, or sharp objects that could damage the cover.
2. Cover Sharp Edges: Use foam or cloth to protect sharp edges like rain gutters or antennas.
3. Position the Cover: Unfold the cover and position it on the roof of your RV.
4. Secure the Cover: Use the straps, buckles, or ropes provided with the cover to secure it to the RV frame.
5. Adjust as Needed: Make any necessary adjustments to ensure a snug and secure fit.
