California adds 12 cent gas tax and 20 cent diesel tax

Bad roads, higher fuel cost, a 55MPH speed limit and stuck in the right lane wonder why I am going to bypass California on the trip back from Washington? And to top that off our RV is old school carbureted and have no issues when in Arizona but let me fill up in California I will start having occasional back fires get back to Arizona after the second fill up no more backfires.
