I'm not a proponent of "inspectors" either. Sure, they will find things, but they'll miss things too.
You will probably miss more "problems" than an inspector would. But the fact of the matter is that a RV will always need maintenance. And my opinion is that a new one will need a lot more fixes in the first few years than a used one would have.
My best advice is to save the money you would have spent on an inspector and put it towards fixing things after the warranty expires. Enjoy getting out and using it, and know beforehand that things will break - it's just part of the deal.
