Here are some things to consider in your quest;
A 2007 model year unit is now, or very shortly will be 2 years old (new model year RV products debut in April), therefore when you drive a 2007 model year off the lot you will loose at least 40% of its value to depreciation. This could be a major consideration depending on your ownership/usage plan for your RV.
I have found that a dealer can, and will, discount current model year units higher than new prior year units, they have less invested. The deepest discounts seem to be on units that are ordered by the customers from the factory. You may find that ordering a 2009 is cheaper in the long run than buying a "New" 2007 model, especially when you bring depreciation and your ownership plan into equation.
If you really want to save $$, look for the 2007 model you are interested in "used".
Good points have been made about "New" 2007 models, tires, batteries, light bulbs, lubricates, finishes and etc. are 2 years old so your "New" product is really an "old" unused product. All the time this "new" product has been sitting on a lot exposed to the elements, with little care. The manufacture will give you the "New" product warranties, but if you check, in most cases, none of the required maintenance has been conducted on the chassis or drive train. Unit may have been shown at many RV shows, therefore seen a lot of traffic. Find out where the MH was manufactured, figure out the mileage between the factory and dealer, the current odometer reading will give you some idea of how much the product has been shown at other venues.
If you decide to buy a unit that is not the current model year insist that dealer/manufacture replace things like batteries, interior light bulbs, conduct required chassis/drive train maintenance, change fluids and tires (especially on 2yr old "new" unit) at a minimum, at their expense not yours. Tire manufactures will tell you that RV tires should be changed after 7 or 8 years of life, the tires on a "New" 2007 unit may already be 2 or 3 years old at delivery to you.
Another way to make up for depreciation loses on a "new" past model year unit is to ask dealer to include the after-market options that you desire , (ie awning packages, solar power packages, sun screens, tow bars, bike racks, extended warranties and etc.), they are more likely to do this than give you discounts. Remember the longer the unit has sit on the lot the more the dealer has invested and owes his banker. RV industry dealers own the products on their lots, so they are stuck with the unit until they sell it, the only time you see units moved between dealers is if the dealerships are owned by the same company, unlike the auto industry.
