Has anyone tried to remove the capless fuel cap on the tank? 2018 KR. I was hoping it was a twist off but wouldn't come off. I'd like to use the larger nozzles at truck stops to fill. My intentions are to tow with my motor home and after filling the MH pull forward and fill the pickup. Is there a trick to remove and even if you did, is the opening them large enough of the large truck nozzles?
