how wide is an rv

It is important to know the width of an RV. Verifying the width of a camping vehicle allows you to judge the space it takes up, preventing accidents. In some states, it is also illegal to own an RV with a larger width than their government mandates.

So how wide is an RV? The answer to that question depends on the RV’s type. For instance, Class A motorhomes have an average width of 8 feet 4 inches. However, this measurement can go up to 8 feet 6 inches, depending on the RV’s specific model.

Below, you will find additional information on why it matters to know the camper width. There is also other relevant data, such as the average width of an RV slide out.

What Is the Maximum Width of an RV?


The maximum width of RV often depends on the region. States like Alabama, Delaware, Illinois, North Carolina, and West Virginia instruct rig owners to have their RVs’ widths no larger than 8-1/2 feet.

If you operate an RV with a larger width than the decreed measurement, you will need to acquire a special permit from the government. It is because a large RV in these locations will become classified as a vehicle with an oversized load.

Additionally, many of the roads in these states do not have the structural strength to cater to many large vehicles. In turn, driving in a large RV on these pavements puts these roads at risk of structural harm.
