I have a 2006 40' Winnebago Vectra on a Freightliner Evolution XC Chassis. It has always been a problem when filling it with diesel. It goes good until you are about 20 gals from full when it starts to burp and shuts off. Then it is a never ending trickle to try and get it full. I have tried opening the opposite side fuel fill and that didn't help. Freightliner has just sort of washed there hands from it saying there is nothing they can do This I simply cannot believe. The vent tube is in place and not plugged. I have tried using the smaller diameter fuel nozzle when I can but can't get this unit into those places. I know this has been thrown around before but just hoping some clever sole out there has found a solution. THANKS
