Based on the posts on other web sites the Wildcat is pretty well regarded. That is not to say that they cannot have problems, but it seems that the problems have been few and far between with that model. Remember that the 07 model is now 1 and almost 2 model years old, so the dealer should be willing to really deal on that one. Besides RV sales in general are really dead right now you should be able to get a really smokin deal on one.
