Arizona DOT fines RV owners for using wrong pump

(Oct. 14, 2014) -- "What this means is those who have a vehicle that has three or more axles or a declared gross vehicle weight rating of at least 26,001 pounds are required to use the truck lanes at a gas station and pay the higher fuel tax," said Koca. "The regular diesel tax is 18 cents. Filling an RV at the regular pumps will subject RVers to a citation with a steep fine."
