Hi everyone. We have been lurking on this forum for about 2 years now because we knew the Montana was the 5th wheel for us and boy have we learned alot. Sold the house, bought the truck..a 3500 dodge dually and a 2009 10th anniv. Montana 3400. We are going full time and are heading for the Oregon coast next week for a month of camp hosting. Can hardly wait. We do have one question..why is the black water drain pipe 11/2 inch and the gray water drain pipe 3inches? Seems it should be the other way around.
Thanks for all the great info on this forum
