Start with the link below - it will have MSRP and also wholesale prices (you do not necessarily have to input your zip).
If you are willing to travel, there are high volume dealers out there who will give big discounts. I got my fifth wheel for over 40 percent off (Holmans in Batavia, Ohio (just outside Cincinnati)). There are others. I ordered mine and got a call when it came in. Then made a run up, did a PDI, and then camped my back to my home base (Florida). Or just pick one from inventory.
