Example complaints

“The Allegro red has two diesel fuel filling ports. It is a rear engine diesel and I fill up at truck stops where they have a fuel pump on either side. Many truck drivers use both pumps to shorted the fill time. However, the passenger's side fill is lower than the driver's side and if you use both pumps, you can overflow the passenger's side fill and spill diesel fuel because the driver's side pump does not know the tank is filled to the level of the passenger side opening. Tiffin is aware of the problem, but no warnings has been posted to owners. …”
