What model do you have? Depending on your model, your dealer can order you a unit direct from Bennington, but you MUST go through a dealer. Bennington does not sell direct to consumer.I have a 20ft pontoon with the bimini top that cover the rear and driver. Can you add a second bimini top for the front? Will the side door interfere with the square tubing attachment? Really wanting some shade for the front.
