Check around with various dealers and different units then make the best deal you can. Tell them you're comparison shopping. It might help. When you find a unit at a price you're comfortable with, and one the dealer is willing to give at that price, You're home. Don't look back after the paperwork is signed and you've got the unit. Can't do anything about it, and grumbling or fretting over it won't help. Nobody forced you to buy or him to sell at that price. If you were satisfied that day, you're done.

I got my Jayco 12HW for 63 cents on the dollar and then turned around the next day and found someone else who had a better deal, so I think JUrban's advice is the best... Once you think it's good, and you found a dealer you feel absolutely comfortable with do it. I'm finding out that I'm really happy to have purchased from my dealer because rv's are not made with the same integrity as automobiles and they've been really good about taking care of my issues.
Good luck with your hunt!
