Well said Walt, buy one that suits your needs and get it checked out they are SSOOOOOOOO similar in they way they are built you would be suprised,by the way seat3a the big 5th's just about ALL have 6 point auto level now. Montana started putting them on in 2012 like mine so no big selling point for Grand designs there they are doing nothing special in 5th wheel construction that makes then better than anybody else They are pretty 5th's though we know three people with them and would recommend them to anybody
