Some states may allow wider vehicles on certain roads or under specific conditions, while others may have stricter rules. It’s important to check the local regulations when planning a route, especially if traveling across state lines. For example, some states may require special permits for RVs that exceed the standard width.

3. Towing Considerations for Wider RVs

• For towable RVs, such as travel trailers and fifth-wheel trailers, the width limits often mirror those of motorized RVs. However, if your tow vehicle and trailer combined exceed the width limit, it may be subject to additional inspection or require a special permit for travel. The width of both the tow vehicle and the trailer must be taken into account when calculating the total dimensions, and exceeding these limits may result in fines or restrictions on certain routes.

4. Special Permits for Oversized RVs

• RVs that exceed the 8.5-foot width limit may require special permits. These permits are issued by local or state transportation departments and are typically required for large motorhomes, custom-built RVs, or fifth-wheel trailers that surpass the standard width. These permits allow owners to travel with oversized vehicles but may come with restrictions on travel times (e.g., no night travel), routes, or additional safety measures, such as escort vehicles.

5. Campsite and Parking Regulations

• RV campsites and parking areas also have regulations about RV width. Most campgrounds have size restrictions for parking spaces, and those with wider RVs may need to book specific sites designed to accommodate larger vehicles. It’s always a good idea to check with your campground ahead of time to ensure they can accommodate your RV’s width. Some parks may charge extra fees for oversized RVs or require reservations for specific large sites.

6. Bridge and Overpass Clearances

• In addition to width regulations, RV owners should be mindful of bridge and overpass clearances. While width is important for navigating roads, the height and weight of an RV also need to be considered. In some cases, bridges or tunnels may have height restrictions, and traveling with a wider RV may require planning around specific routes that accommodate these limits.

Understanding RV width regulations is essential for safe and legal travel. While most RVs are designed to meet the standard 8.5-foot width limit, those with wider vehicles may need special permits and should pay close attention to local, state, and campground regulations. Planning ahead, checking permits, and being aware of road and campsite restrictions can ensure a smooth and trouble-free RV experience.

Measuring the Width of an RV

Measuring the width of an RV is an important step to ensure that the vehicle fits within legal size limits, can navigate certain roads, and is suitable for parking at campgrounds or other destinations. The width of an RV can vary depending on its type, design, and any added features such as slide-outs. Here’s how you can accurately measure the width of your RV.

1. Measure from Edge to Edge of the RV’s Body

• The simplest way to measure the width of an RV is to take a tape measure and measure from the outermost edge of the left side to the outermost edge of the right side. This includes any side mirrors, awnings, or other protruding features that may extend from the body of the RV.
• Note: The official width measurement typically excludes items like mirrors or accessories that are removable or not part of the RV’s permanent structure.

2. Consider the Width of Slide-Outs

• Many RVs feature slide-outs that extend outward to provide additional living space when the RV is parked. These slide-outs add to the width of the RV but only when they are extended. To measure the RV’s width accurately, you should measure both with the slide-outs retracted and extended.
• Retracted Slide-Outs: Measure the RV’s width as described above, excluding the slide-outs if they are fully closed.
• Extended Slide-Outs: If you need to measure the width with the slide-outs extended, be sure to include the extra space they occupy in the overall measurement.

3. Account for Add-Ons or Accessories

• If your RV has additional features such as external storage compartments, awnings, or rooftop accessories (e.g., satellite dishes or air conditioning units), make sure to measure these as well if they extend beyond the RV’s body.
• Tip: Most measurements are taken from the outermost edges of the vehicle, so these add-ons could influence the final width measurement.

4. Check Manufacturer Specifications

• Most RV manufacturers provide the exact width measurements of their vehicles in the owner’s manual or on the product’s specifications sheet. These measurements are typically taken at the widest point of the RV’s body, excluding mirrors and add-ons. If you’re unsure about how to measure, referring to the manufacturer’s measurements can provide clarity.
• Tip: Always check the width with and without slide-outs or other expandable features for accurate comparison.

5. Use a Vehicle Registration Document

• If you have access to the vehicle registration documents, you can often find the RV’s width listed there. However, keep in mind that this measurement might not include slide-outs or other accessories, so you may need to measure those separately if you want to know the total width at any given time.

6. Consider Roadway and Parking Requirements

• When measuring the width of your RV, be mindful of the legal width limits for vehicles traveling on the road. In the U.S., the maximum width allowed without a permit is typically 8.5 feet (102 inches). Measuring your RV accurately is critical to ensure you comply with these regulations and avoid potential fines or issues when driving or parking.

Measuring the width of an RV is straightforward, but it requires careful attention to detail, especially when slide-outs or additional features are involved. By measuring from edge to edge and considering the inclusion of slide-outs or accessories, you can ensure that your RV fits within legal guidelines and is suitable for your travel and parking needs. Always double-check manufacturer specifications and be mindful of local regulations when taking your RV on the road.
