Lenght of RV and trailer

Also Tom/Barb, the Federal Highway regulations set minimum weights and vehicle sizes that the states are required to allow. For example California limits vehicle combinations to no more than 65 feet. However, I believe the federal standard says 75 feet on the Federal Highway system. So California has to allow commercial vehicles to 75 feet on the Interstate and for reasonable access routes. Federal law does not say a State has to allow Triple Towing. But it doesn't prohibit it either. So states like Nevada allow it, but California does not (without permits or some special exemptions.)
