Arizona, Nebraska, New Mexico and Virginia recently approved bills to allow motorhomes as long at 45 feet within their boundaries, according to the Recreation Vehicle Industry Association (RVIA).

Previously, motorhomes longer than 40 feet were not allowed to use the roads in the four states.

Currently, 35 states allow motorhomes as long as 45 feet and Illinois allows motorhomes as long as 42 feet.

Length legislation is pending in eight other states, including California.

“Length uniformity for motorhomes is a top priority for the association,” said RVIA President Dave Humphreys. “We hope that the recent bills passed in Arizona and New Mexico will help our efforts in California.”

Now, California, the largest RV market, is the only state in the western U.S. not allowing motorhomes longer than 40 feet, Humphreys said.

State motorhome length legislation usually is tied to licensing requirements. In California, the gross vehicle weight rating (gvwr) may end up determining whether the owners of larger motorhomes will need a special license to operate their coaches in that state.

California might decide to ignore the length and require the owners of motorhomes with a gvwr of 26,000 pounds and above to get a “special endorsement” to their driver’s license.

Passing a medical and a driving test would be required to get a special endorsement in California, which would not be as rigorous as getting a commercial driver’s license.
