Fuel Cost in Arizona?

I am not sure what this means, IS a person with a Class A Motorhome required to purchase Diesel at a special pump? We are planning on spending the winter in AZ and would like clarification prior to getting there. Thank you,

Diesel Fueling in Arizona
Messag e from Jim Koca, Advocacy Director


Arizona fuel-tax rates are different from what we may be used to while traveling throughout the United States. This fuel law has been on the books for several years. The law states:

The Arizona tax on gasoline (motor vehicle fuel) is 18 cents per gallon. Use fuel (diesel) is taxed at two rates in Arizona.

-If the use fuel is used in the propulsion of a use class motor vehicle on a highway in this state, the tax rate is 26 cents for each gallon.

-A "use class motor vehicle" means a motor vehicle that uses use fuel on a highway in this state and that is a road tractor, truck tractor, truck or passenger carrying vehicle having a declared gross vehicle weight of more than 26,000 pounds or having more than two axles.

I talked to the Revenue & Fuel Tax Administratio n Fuel Tax Manager in Phoenix, Az, and asked for the definition of the "passenger carrying vehicle" and he stated that would include a motor home. What this means is those who have a vehicle that has three or more axles or a declared gross vehicle weight rating of 26,001+ lbs are required to use the truck lanes and pay the higher fuel tax. The regular diesel tax is 18 cents. Filling the RV at the regular pumps will subject you to a citation with a steep fine. Arizona has a Fuel Tax Evasion Unit that monitors the filling of vehicles at fuel stations.

Escapees feel that this information should be sent out to all of the members that travel through Arizona.

I would like to thank all of the members who have sent in this information to Headquarters so that we could investigate this issue.
